Zakopane has a very active apres-ski scene, clubs include va va voom, blue star and prestige.
It's a lot more expensive than the rest of Poland however and it can get very crowded so be prepared to fight to get served.
With very artistic interior and exterior, the Cafe Piano is the most unique bar in Zakopane. It is located at the upper left of the main street. If you go up from the bottom, you will find an artistic sign made of gray sheet metal and yellow plastic. All of the counter seats are swings, so you need less drink to get drunken. :-) It opens at 15:00.
Dress Code: None.
Krupowki is the place to be for bar hopping and you'll have plenty of choices along this street. I had a beer at a place simply called "Drink Bar" which was a tiny little place just across from Reserved (the clothing shop). Another good place is Cafe Piano, a pub just off of the main street that has a really cool interior with swings for barstools and a good drink selection.
There are 3 of them in the chain so far, the one in Krakow, in Warsaw and in Zakopane. This one is bigger than Krakow Paparazzi, it has a room with few kind of boxes and fire place. There is the same menu in both cities - excellent drinks, few pastas and sandwiches.
The worst thing in Paparazzi is its service, the waitresses are not professional at all, stuck up and not nice at all... unless they feel a big tip.
Dress Code: No special dress code... especially that you're in the resort in the mountains.
This time we were partying in Natalia's cottage and we had lots, lots of fun. It was one of these evenings when you just can't stop laughing.... :-)

Your best bet is to hit one of the cozy underground pubs. There are some nightclubs here too on the main street, and most of them had a cover of about $5.
