Kassen sits on Nørrebrogade just over the lakes in Copenhagen, a late night cocktail bar that runs frozen drinks under a ceiling of disco balls. The room gets loud, the crowd gets dancing, and the bar stays open until 4am on weekends. This is the Nørrebro spot built for the part of the night after dinner ends.
VisitCopenhagen files Kassen as a cocktail bar, and the house specialty makes the case fast, which is the frozen cocktail. The bar leans on slushie machines for frozen daiquiris and margaritas, and the disco balls set the tone for a dance more than a sit down. It works as a social room first and a cocktail bar second, in the best way.
The space runs dark, glittering, and packed on a Friday, with a long bar, a small floor, and mirror balls throwing light across the crowd. The layout favors movement over lounging, so expect to stand, dance, and call your order over the music. The energy is the entire draw.
Order a frozen cocktail, because that is the reason the room exists. The frozen daiquiri and frozen margarita lead the list, and happy hour runs two cocktails for 85 DKK on weeknights and all evening on Wednesday. On Thursdays the bar runs an open bar at 250 DKK, which keeps the student crowd deep and the floor full.
The crowd skews young, local, and ready to move, with Nørrebro regulars and a steady run of students. It picks up after 11pm and peaks toward closing, when the weekend hours stretch to 4am. People come for the last drinks of the night and stay for the floor.
Go Friday or Saturday for the full disco ball treatment and the 4am close. Come Wednesday or Thursday for the happy hour and the open bar deal if value drives the night. Skip it if you want a quiet craft cocktail and a real conversation, because Kassen is a loud, frozen, dance first bar.
What regulars flag most is the frozen drinks and the price. Yelp reviewers, updated June 2026, keep returning to the same notes, which are cheap cocktails, disco balls, and a room that delivers a night out without a cover charge. The value and the energy carry the headline.
The location puts Kassen on the busy stretch of Nørrebrogade right by Dronning Louises Bro, a five minute walk from the lakes and a quick bus ride from the centre. The bridge crowd spills in on warm nights, and the bar sits close to the late food counters that keep the area moving past midnight. Pair a frozen daiquiri with the first hour and a frozen margarita with the floor, then chase the night with a shawarma on the walk home, because Nørrebrogade keeps the best late counters in Copenhagen.
Who it is for: late night dancers, students chasing a deal, and groups who want the back half of the night handled in one room. Who it is not for: anyone after a refined cocktail program or a calm table for two, since Kassen runs hot from open to close.
Kassen belongs in the Copenhagen cocktail and late night conversation alongside the city's other essential rooms. Drink it next to the basement classics at Ruby in Copenhagen, the apothecary list at Lidkøb in Copenhagen, and the playful drinks at Duck and Cover in Copenhagen.
