When I was at uni up in Leicester in late 90s I remember having some great nights up Flaming Colossus- helped that I went a couple of times in a group along with the lovely Vivien Solari and her mates before she got whisked off to the NY catwalks! Mozzie Coast and Le Palais De Dance were also good laugh on student nights too and I became a dedicated follower of Passion after I was introduced to the Emporium in (the middle of nowhere!) Coalville.
After moving back south in the early 00s I used to go clubbing up London a couple of times a month. Big Beat Boutique Vs Bugged Out at Fabric was always great as was The Gallery at Turnmills, which has now unfortunately closed to make way for some flats

Also went to a couple of raves at Camden Palace before it was changed into Koko. The 2 times i went to Ministry of Sound i didn't enjoy much though as it seemed to be full of poseurs and tourists.
Nowadays I don't think I could manage an all night clubbing session up London and there aren't any decent clubs nearby since Empire and the Sanctuary in Milton Keynes closed down, so the closest i get is when someone decides to have their birthday up one of the local Luminar venues
