I'm still not really understanding the whole "Brighton's nightlife ain't that great" argument. It is a city of 250,000 people. You have to compare it against cities of similar population size (like Southampton and Portsmouth) which it's far better than. It has tons of great pubs and clubs, you can go clubbing and find a good night in terms of price, atmosphere and music on any night of the week. Most bands will go through Brighton on tours. Okay, not quite so great at weekends because of all the stag and hen do's coming down and the out of towners but apart from that it's great.
But yeh I've done these arguments to death anyway before.
