dry dock is quite good actually, tuesdays is £1 a pint and other very cheap drinks, packed with scene kids though which sucks, but any other night is usually okay. the library (further up towards hyde park) is better, ran by the same company, same prices etc, but just nicer.
cockpit on saturdays is pretty good, mainstream american tunes basically (jimmy eat world, head automatica) which is very singable to when you're fully intoxicated.
carpe diem is a basement pub just off the headrow i think it is, which does some good gigs and some good music aswell. check out Trash in the main town (underground bar) which sometimes has some good bands on despite looking like a craphole.
oceana on a tuesday is alright until about 11pm when they shut all of downstairs and then all is left is the oldies on the upper floor?? weird.
