I'm from London :P
It's alright but i suggest you mix it up a bit. There's probably about 7 - 8 clubs that you can go to minus a ****load of pubs (one for every day of the year as the myth goes). Am currently sick of Optic and Ponanas...funnily enough, i'm going to Optic tonight.... <groans>
Optic - Cheese n stuff, best night is Monday.
Ponanas - Alternative/Indie, best nights Monday, Tuesday, Thursday.
Waterfront - Union owned, depends what night you go on but usually Alternative, 80s, and that Sadomasacist thing where everyone dresses in tight PVC suits and have strange piercings. Best nights Fridays and Saturdays.
Mustard Lounge - Alternative, Wednesdays i think are good.
Sonic - Extremely Alternative. Some weird music there...every other Thursday i believe. Careful you don't go to gay night by accident.
Mercy - Your local run-off-the-mill mainstream R'n'B club. Tuesdays and Thursdays.
Lava/Ignite - Two clubs, one is pretty eclectic cheese/pop the other R'n'B. Tuesdays and Thursdays.
