For clubs on Friday the biggest would probably be Bodega (Soul/Funk) and the Savoy (Indie-ish). Not sure if either are your cup of tea the Liquid Lounge has Miss Motif this Friday (not sure what she's like, House/Techno/Electro) and Fast Eddies as usual has dance stuff on a Friday (better on a Saturday with Fish Go Deep), City Limits is an indie greatest hits night (yawwwn) and there is a Techno night in the Tikki Lounge, so all in all something there for everyone. Casual Dress Code for some of the above though could be a non runner especially the Bodega and Liquid Lounge (excuse the pun!!).
Hope you have a good night lads except for the result of course.
