I spent nearly 2 weeks in Bratislava a few years ago and had the best time! This was back in 1997, so I don't really remember the places I went to. The one I do remember, I can't spell! It's called U Mamicy or something like that. There was also a club at the Forum which wasn't too bad.
I've heard that Bratislava's changed dramatically in the last few years. They've a Buddha Bar now and you even get Chinese, Indian and Thai food!
I was there with a friend during New Years last year.
Here are a few places that I went to:
Cocoloco - A cocktail bar with a fairly cool interior, but fairly small.
Chicago - A fairly good club
Life Club - A HUGE club, very good place.
Peoples- Lounge. Good place to start off the evening after dinner. Owned by the restaurant mentioned below
Dining: Paparazzi - It is located in the heart of the city just a few blocks away from the SAS hotel. Excelent food for reasonable prices. (italian)
Another tip: Dont get into a fight or you will definetly get the $hit kicked out of you! Watch your attitude towards others and dont be too loud either.
Another thing: Everything is dirt cheap, except for the restaurant I mentioned
