What do you want? A big place with dancing, or just a neighborhood bar?
For dancing try the Saloon on Hennepin. A quieter bar a few blocks down is the Brass Rail, though the clientele is a bit old.
The Mpls Eagle is on Washington. Tame until the sun goes down, then it changes. On weekend evenings you may find a leather dress code enforced. It includes the Bolt, and the Bolt Underground. I've seen all kinds of BDSM stuff down there, hot waxings, floggings and bondage, if you like that.
For a very quiet neighborhood gay bar there's the "19". Nothing special, just a bar.
If you like drag, the Townhouse in St. Paul puts on shows. Another small neighborhood bar, but it's a mecca for the drag crowd.
