I lived in Nottingham for a few years, the club scene isn't very good.
The best place to go clubbing is Stealth
Bars
in Hockley - Browns, Social, Hockley is the best place to go for bars, loads of little ones down all the back streets. They are easy to find
Lace Market - Bluu Bar, Dogmar
There is also a bar at the top of the cinemar complex, it has a roof garden, sorry I can't remember the name.
