About Mosaic
Mosaic Ultra Lounge is a high-energy nightclub and lounge in downtown Baltimore, anchoring the Power Plant Live! entertainment complex near the Inner Harbor (powerplantlive.com ) (powerplantlive.com ). The venue is sleek and modern – described by its owners as “sleek and sophisticated” with plush seating, an outdoor patio area, and vibrant lighting elements (powerplantlive.com ). It’s known locally as a “swanky” spot with DJs spinning Top-40, pop and house music, and offers VIP bottle service and champagne by the glass for a upscale experience (powerplantlive.com ) (wanderlog.com ). Mosaic’s total capacity is roughly 550 people (about 400 inside the club and another 150 on the covered patio) (powerplantlive.com ), making it a mid-sized venue compared to Baltimore’s larger arenas. While Mosaic doesn’t have a decades-long history, it’s part of the revitalized Power Plant Live! district that brought new nightlife and dining options to the city (powerplantlive.com ). It matters to the local scene as one of the few late-night dance clubs right in the heart of the city, attracting young crowds on weekends and after Baltimore sports and Inner Harbor events.
Events and Programming
Mosaic is primarily a nightclub hosting dance parties and DJ-driven events. It’s best known for electronic dance, EDM and Top-40 DJ sets, but the programming can span styles from hip-hop to even country beats on special nights. The venue regularly presents club nights called “Mosaic Presents” on Thursday and Friday evenings (powerplantlive.com ). Past lineups have included touring EDM acts like Delta Heavy and Dirt Monkey, as well as bass and dubstep DJs (for example, the 2025 schedule included shows by Delta Heavy and Dirt Monkey) (www.bandsintown.com ). The club also hosts themed events: for instance bingo-rave nights (“Bingo Loco”), foam parties, and specialty tour dates like the “Hot Country Nights” series (it hosted country band Parmalee in 2025).
In addition to big name DJs, Mosaic has weekly recurring parties. It promotes a monthly Ladies’ Night (the last Saturday of each month, often with free entry for women) and a Birthday Night (on the first Saturday of a patron’s birthday month, also with specials and no cover) (powerplantlive.com ). There are often drink specials and fun themes on these nights. On non-chart nights, the club still runs DJs and dance music, so almost every weekend features something lively. Special late-night events – such as “Friday Night Live” series or DJ showcases – take place frequently. Overall, Mosaic’s calendar combines recurring club series, one-off DJs and live acts, and novelty nights, so check the schedule to see what fits your taste.
Tickets and Booking
Tickets for Mosaic events are mostly sold online. When headliner DJs or special events are announced, tickets go on sale typically through official ticketing partners like AXS or SeatGeek. The Power Plant Live! event pages usually link to those ticket sites – for example, a concert page may have a “Buy Tickets” AXS link (powerplantlive.com ). Tickets often range from around $20–$30 for general admission shows (plus fees) (wl.eventim.us ), though some smaller club nights may be cheaper or even free (just a cover charge at the door). VIP and table service options (requiring higher spend and large party reservations) are also available by contacting the club or booking through LiveDistrict VIP services. In practice, if you plan to catch a specific DJ or concert at Mosaic, we recommend buying online early – popular shows can sell out and have ticket limits (e.g. one promotion stated a 10-ticket limit per buyer (wl.eventim.us )). If an event isn’t sold out, there is often a limited number of tickets at the door or a cover charge, but don’t rely on that for big shows.
Seating and Layout
Mosaic is a general-admission club rather than a theatre with fixed seats. The main floor is an open dance space in front of the DJ booth, surrounded by a perimeter of lounge seating and bars. You’ll find couch-and-table sections along the sides and back of the club, which are usually reserved for VIP bottle service customers. The covered outdoor patio (on one side of the club) provides additional seating and a view back into the club’s events. Because it’s mostly standing-room, the “best” vantage depends on what you want – near the DJ is great for an immersive dance experience, while the café-style lounge seats are better for socializing or catching a break from the crowd. Note that like many nightclubs, Mosaic’s sound system is very powerful (think high-output club audio) – it uses a professional PA to keep even bass-heavy music clear at high volume. Guests sensitive to loud bass might want to hang back from the subwoofers or step onto the patio occasionally. The club features LED lighting and video screens to enhance the atmosphere around the dance floor. In general, the layout is flat and open, so sight lines are good; there are no hidden corners, and you can usually see the DJ from anywhere on the floor or on the patio.
Getting There and Parking
Mosaic is located at 4 Market Place in downtown Baltimore (at the corner of Pratt Street in the Power Plant Live! complex) (powerplantlive.com ). It’s just a short walk from many harbor-area landmarks and transit stops. Public transportation options include Baltimore’s Light Rail (the Convention Center or Camden Yards stops are nearby) and the Metro Subway (Shot Tower/Charles Center station is a 5–10 minute walk from Pratt). Several MTA city buses serve Pratt Street and Commerce Street right by the venue; notably Bus 40, Bus 78, and the CityLink Blue/Navy/Brown lines all have stops within a block (moovitapp.com ). The free Charm City Circulator (Purple or Orange routes) also stops a few blocks away, or you could take the Inner Harbor water taxi to the nearby pier. For drive-up traffic, the area around Power Plant Live has multiple garages. The Hilton Inner Harbor garage (301 W. Lombard) and the Harbor Park Garage (55 Market Pl) are within a 5-minute walk, and street parking or have-lots can be found on Pratt or in the stadium district. Rates in downtown garages typically run around $10–$20 for an evening; it’s wise to reserve via an app or pay in advance if possible. Rideshares (Uber/Lyft) and taxis can drop guests off on Pratt or at the Stock Exchange corner of the PPL courtyard. Always allow extra time for arrival, especially on game nights or weekends when traffic is heavy.
Inside the Venue
Expect a bustling club atmosphere. At the door, staff will check your ID and ticket or collect cover charge; Mosaic enforces a 21+ age policy for most events (powerplantlive.com ). Security guards typically scan bags or use a wand for safety. Inside, the club is dimly lit with colorful lights and occasional strobes; it tends to be packed on weekend nights after 10pm. The bar area serves full cocktails, beer, wine, and shots. Mosaic specializes in cocktails such as martinis and signature mixed drinks, often at club pricing. There isn’t a kitchen, so plan to eat before you come (the Power Plant Live complex has restaurants like Luken’s BBQ, PBR Baltimore, and a casual food court area if needed). There is a small merchandise or retail station on occasion, especially during special concerts, but mostly just drink service. Restrooms are located inside (and likely ADA-accessible). If you check coats, note that during winter months a coat check may be available for a fee. Overall, the vibe is upscale clubby – people often dress “club-smart” (no athletic wear, etc.) and socialize on the dancefloor.
Nearby Amenities
Mosaic sits in a dense spot for dining and nightlife. Within a few blocks you’ll find many pre-show restaurant choices: Phillips Seafood, McCormick & Schmick’s, Hard Rock Café and local seafood eateries line Pratt Street; pizza and bar-food spots like RedBrick Station and Bond St Social are on Commerce. For a quick bite before hitting the club, Bill Bateman’s Bistro (pizza and seafood) at Harborplace and Calvert Street is a local favorite. If you want a bar atmosphere before or after, the building itself houses PBR Baltimore (a brewpub), Lucky Strike (bowling and bar), and Rip City Rock Bar (rock’n’roll-themed lounge). A block south, Off the Hook Seafood and Pho 88 have late-night hours. Beyond food, hotels abound: High-end options include the Four Seasons and Pendry (1/2 mile away) or the Royal Sonesta and Hilton near the aquarium (~10 min walk). More affordable stays like the Courtyard/Residence Inn, Aloft, and Homewood Suites are near Camden Yards. If you arrive early, the Inner Harbor promenade is pleasant for a walk. After 2am, most restaurants close, so plan accordingly (some nearby bars near Lexington Market or Fell’s Point stay open later). Also note that trains and light rail generally stop service around midnight on weekends, so arrange your exit plan or rideshare pickup ahead of time.
What Makes This Venue Special
Mosaic may not have a century-old legacy, but it fills a unique niche in Baltimore’s cultural scene. It’s one of the few true nightclub experiences downtown, blending sleek, modern design with an indoor/outdoor setup. The indoor dance floor opens onto a covered patio, a layout reminiscent of similar clubs in Cordish’s Power & Light districts (www.avnetwork.com ). This allows an open-air feel even late at night. It’s a stage for rising DJs and touring electronic acts in a city that’s better known for jazz and rock. Local tradition holds that Mosaic is the go-to after-party spot for Orioles/Ravens games or sporting events at Camden Yards and M&T Bank. Artists like Bingo or DJs often pop by after festivals or late shows since Baltimore doesn’t have many late night dance venues. Economically, Mosaic contributes to downtown revitalization (the Power Plant Live complex cites being “Baltimore’s dining & entertainment destination” (powerplantlive.com )). It brings nightlife workers and patrons who then also support nearby restaurants and businesses. The club atmosphere – from the multimedia LED walls to the VIP lounges – appeals to both locals and out-of-town visitors looking for urban nightlife. All these factors give Mosaic its special character as a staple of Baltimore’s after-dark entertainment.
Visitor Tips and Information
Accessibility: Mosaic is on ground level with wheelchair-accessible entrances and restrooms. If you need accommodations, it’s best to call ahead or ask staff. Dress Code: Standard club attire is expected (no athletic shorts or sneakers). Doormen may turn away guests in overly casual clothes.

Large bags or outside drinks aren’t allowed, and phones or small cameras are fine but tripods are not. Common Pitfalls: Don’t rely on street parking – plan for a garage if driving.

And be prepared for fun – mosaic’s energy level stays high into the early AM, so go with a group and enjoy the music!

There’s also a garage under the National Aquarium (801 Key Hwy) and several lots around M&T Bank Stadium. Expect to pay around $10–$20 for an evening. On-street parking is limited.

Which public transit stops near Mosaic?
Power Plant Live (Mosaic) is well-served by transit. The Light Rail’s Convention Center stop and the Metro Subway’s Shot Tower/Charles Center stop are both within a 5–10 minute walk. Bus routes such as the CityLink Blue, Brown, and Bus 40/78 stop on Pratt Street nearby (moovitapp.com ). The free Charm City Circulator (Orange or Purple routes) also has stops near the Inner Harbor that are a short walk away. Late-night visitors often use Uber/Lyft since buses stop running by midnight.
What is Mosaic’s dress code?
Mosaic enforces a smart-casual dress code. Club-chic attire is recommended – think nice shirts and shoes for men and dresses or stylish tops for women. Avoid athletic wear like jerseys, shorts, or running shoes. The door staff can refuse entry for overly casual or sportswear outfits. Generally, it’s best to dress up rather than down for this lounge atmosphere.
Can I bring a camera or bag into Mosaic?
Small personal bags or clutches are usually allowed but will be checked at the door. Professional cameras (DSLRs, video cameras) and large gear are not permitted without special permission. You can bring your phone and casual camera for snapshots. Lockers are not provided, so keep belongings light. Alcoholic beverages or outside food definitely cannot be brought inside.
Does Mosaic have seating or tables?
Aside from a few lounge couches and high-top tables around the edges, Mosaic is primarily a standing-room dance floor. General admission is all on the open floor or patio. If you want a table, you’d need to reserve a VIP table service in advance. Otherwise, plan to stand or grab a couch spot when you arrive early. Everyone shares the main floor and patio area.
Are there age restrictions at Mosaic?
Yes. Mosaic Nightclub is strictly 21+ on weekend nights and for most events (powerplantlive.com ). All patrons will be carded at the door. Occasionally special events (like company parties) might allow younger ages but those are exceptions. Always bring a valid ID; anyone under 21 will be denied entry.
Are the bathrooms in Mosaic wheelchair accessible?
Yes, the club is designed for ADA accessibility. There are wheelchair-accessible restrooms and the entrance has ramps. Because Mosaic is on one level and in a modern building, guests with limited mobility can navigate inside. If you have specific accessibility questions, call ahead – the venue staff can assist with any accommodations needed.
What food and drinks are available at Mosaic?
Mosaic itself only has a full bar and no kitchen. You can order cocktails, beers, wines, and late-night snack cocktails (like mixed beverages) at the bar. The Power Plant Live district has many restaurants if you need a meal – the club does not serve food. Drink prices are typical for city nightclubs (cocktails around $12–$15, beer around $7–$8). Happy hour specials at nearby PPL bars do not apply inside Mosaic.
Is there a coat check or lockers?
Mosaic usually offers a coat check during the winter months for a small fee, but not year-round. There are no lockers. If it’s chilly, expect to surrender your coat at the door and pay about $5–$7 to retrieve it later. In summer, this is generally not an issue. Always get a claim ticket for your items.
What time does Mosaic close, and when should I arrive?
On Friday and Saturday nights, Mosaic is open until 2AM (doors 9PM–2AM) (powerplantlive.com ). Weeknights or special events may vary. Because lines can get long on busy nights, arriving before 10PM is wise if you want to beat the crowd. If you have a ticket to a particular event, aim to get there early to use your ticket before any potential lines. Public transit runs only until midnight-ish, so plan your exit (or stay later and use a ride share).
Are there any regular weekly events to know about?
Yes. Every week Mosaic often runs “Mosaic Presents” club nights on Thursday and Friday with their DJs (powerplantlive.com ). It also advertises a “Lady’s Night” on the last Saturday of the month and a special birthday month party on the first Saturday (powerplantlive.com ). There may be changing monthly themes, bingo or trivia nights, or holiday events. Check the club’s website or social media for the current schedule of recurrent nights.
What is the “no re-entry” policy?
Mosaic typically does not allow re-entry. Once you leave the club, you will not be permitted back in under the same ticket or cover entry. This is common for busy clubs, so be prepared to keep your personal items with you or leave them in the coat check. If in doubt, treat one arrival as final for the night.
