in Glasgow i can recommend & warn u off of...
Subculture @ Sub Club (sat) - not been myself but have only heard good things - Depp House the main style but covers tech-house, hip hop etc
Optimo @ Sub Club (sun) - again not been but friend swears by it - very eclectic night a la 2manydjs style
Offset @ Cube (fri) - usually a cracking night, house in main room, sometimes guests like Scumfrog, Sandy Rivera etc
Pressure @ The Arches (last fri of month) - Slam promoted night - 1 arch house, 1 arch techno - top quality djs every month in a real underground feel venue
Colours @ The Arches (first sat of month) - usually good but recently booking cheese - guests include sasha, digweed, morillo, deep dish - normally either prog house house
Groovejet @ Trash (sat) - not a big ngiht but the house room is hosted by the former Tunnel room 2 djs - playing good house music with the odd Tunnel classic thrown in - usually ending with classic trance for a couple of tunes. good banter with the djs too - they are usually more drunk than the crowd!
The Garage - student venues, crap music, worse crowd
Archaos - ned-fests, most likely places to get trouble, cheesy trance zones
Most clubs in Glasgow now run the 2 room basis - 1 playing house music, the other playing commerical RnB - avoid the RnB rooms like the plague!
