I went about 8 year ago now when it was just taking off. It was crazy then and every single bar you went to wanted you to dance on the bars and drink fishbowls full of cheap mix up's. IIRC there aint many clubs, there small and its mainly bars open late. The pubs are better to stay in anyway. Chances are its probably changed alot since I was there though.
I went in August and it was boiling, hottest place I've ever been. My mate also done in 2 local bouncers and booted out a taxi drivers headlights/front grill and couldnt go out for the last 4 nights. We were warned the local "mafia" were after him lol!
EDIT:
All the best pubs were on a main street that was open late with loads of shops and stalls at the bottom end. Oh and I remember 2 clubs, one in a church/cathedral renovation and "Underground". Someone tell me if its changed much....!?
