The local scoop
510.2 is the prohibition-themed lounge in the same downtown Bismarck building as LÜFT Rooftop Bar. The operator’s dedicated 510.2 page calls out signature craft cocktails, classic mixed drinks and specialty whiskeys and bourbons. It also describes an intimate setting for music and private gatherings. The lounge and rooftop serve different moods, so this page focuses on the indoor cocktail space rather than the rooftop above.
What they're serving
- Signature and classic cocktails
- Specialty whiskeys and bourbons
- Intimate indoor lounge for music or gatherings
Before you head over
The operator lists its downtown location at 510 East Main Avenue. Its public 510.2 page does not give a dependable weekly schedule or direct phone number, so confirm opening and entry details with the venue before making a dedicated visit. The same address also houses LÜFT; ask for 510.2 if you want the indoor lounge.
