In terms of bars - Daks (attached to Snezhankha, turn right out the hotel door and you will see it) is usually good and certainly convenient.

For immediate apres-ski then The White Dog just above where you get the buses from at Ski Centre 2 is good - but if you miss the bus you will have a 40 min walk back or a rip-off taxi. You will have a good time - don't go overboard though, the reps kicked out a group last week for smashing a room and they lost flights/transfers/hotels etc!
Clubs - not sure I'm afraid, but someone else will probably help out below
