In many dance venues, you can just sit and enjoy a drink, while quite a few bars and pubs will have a dancefloor. It's up to you to sample the different places and decide which one suits you best.

Szimpla Kert
For the first drinks in the evening a cool place is Szimpla Kert, which is a bit more on alternative side and probably better in summer but a great place to go and seems like always full of people. And don't be turned off by the interesting "doors". There's a great place behind them.

Henri Belgian Brasserie
Laid back place that serves a fine selection of Belgian beers. This is a gem of a bar and a must visit for anyone seeking a good Belgian beer experience. They have a great selection including all the favourites, Duval, Rochefort, Leffe etc. all accompanied by branded glasses and in most cases branded beermats.

There were also some interesting bottles of Kwak, Judas and Guillotine. All were given well informed reviews in the menu which contained this excellent description of Delirium Tremens.

Süss Fel Nap
Laid back and unpretentious place where you can just have a good time hanging out with friends. Great hiphop n r&b on saturday nights.

Szoda Bar
For a couple of drinks and dancing a great place is Szoda bar. Upstairs for drinks and downstairs for dancing!

Piaf
Anyone with vaguely Bohemian leanings seems to wind up at Piaf, a stylish and sophisticated night-club, named of course, after the famous French Diva.

Red velvet furnishings abound, while the music (which is often provided by a resident pianist) has a distinctly jazzy feel. This place is open late (until 7/8 am) and the locals are generally friendly - a good place to meet hungarian ladies. Beer isn't too expensive, expect UK prices for spirits.
