Nightlife in Copenhagen changes fast and starts late. Most clubs only begin to fill up around midnight. New clubs and bars spring up regularly. Some of the newer additions include: Subsonic, featuring a 'preserved' Bier Keller corner, a large dance floor and a perfect copy of a SAS lounge with original aircraft seats. The music is predominantly 80’s dance. Also new is Fever in the old X-Ray club, which is a Hip hop and R&B club. A relaxed lounge area makes it a good place for an earlier start, with the dance floor picking up around midnight Friday/Saturday only. 

For a completely different experience, there's Base Camp, a hangar like venue on the newly revamped military island, Holmen. As well as a nightclub and 'The north's biggest restaurant' with 600 seats, it's got an outdoor grill area with live music.

An interesting pre club bar is Stereo Bar around Israels Plads, which offers 70’s retro decor easy listening and lava lamps. Music ranges from trip hop, drum & bass to latin/jazz. Ideal Bar, in Vesterbro is also an early starter, which picks up speed as the night wears on, developing into a fully fledged dance club featuring funk, latin, easy listening and swing beat.

Clubs and venues :

Vega, one of the city's most characteristic venues, features both big names from the rock and dance world and underground acts on it's smaller stage. Based in a 1950's trade union building, the interior has been retained right up to the fifties glass light shades giving it a unique atmosphere, from its zigzag tiled floors to its 60’s mural decked bar. For a more underground feel, Stengade 30, in Nørrebro features the best of Danish and international rock and dance acts, usually with an all-night club to follow. Also in Nørrebro, Rust, a primarily live music/dance venue has an outdoor yard and bar. Its packed club nights have a relaxed free-style dance-floor policy.

Pure dance clubs are also thick on the ground, Fever, Slide and Nasa, all in Baron Boltens Gård are worth a visit. However, as Nasa is a private club, it may be hard for visitors to get in - admission are preferably granted non-members who look like models or money. Right next to Tivoli in the old Jazzhouse Slukefter there's Club Mantra which play perhaps the best R&B and hip-hop in town. A luxurious interior, white leather sofas and a panoramic mural of Copenhagen at dusk, combined with the beats makes this THE place for cool Copenhageners. Over in Østerbro there's the more established Park Diskotek, the relaxed home of happy house. Copenhagen's gay scene is loosely based around Sebastian and the popular three storey Pan Disco, as the focal point for dancing.
You might try to use the mobile night life guide Mobileclubbing that also lists all the gay clubs. It is found on your mobile phone on www.mobileclubbing.net.
For jazz, Copenhagen Jazz House is the best option. With the renewed interest in new Danish jazz, this intimate showcase club features international and Danish acts, with a club night on weekends is popular with the younger Copenhagen jazz crowd.
