I've been to two shows there. The Stellastarr show of a few weeks ago had one opener and was done well before midnight, which was good.
However, the Horrors show was a mess. The Web site listed three bands starting at 9:00 pm, until the day of the show when one of the openers disappeared, though the 9:00 start-time remained the same. As it happened, there were no opening bands, and the Horrors didn't start until after 11:30. But they only played for 20-25 minutes, so it still wasn't a late night.
