Bars I would suggest are:
Stereo - Quayside
Tokyo - Nr Central Station
Other Rooms - Next door to Digital
55 degrees - on the middle of a roundabout in centre of town - but dont let that put you off!!
These are the only bars I go to to be honest - so these are my personal choices, depends what you type of bar you like - are you up to pull or just for a dance and carnage session?
