I tried to go here on a Friday night in July 2008. It was 9 p.m. when I got to the door, and still an hour to closing time, but they wouldn't let me in. They actually had a busboy keeping his hand on the door to not let anyone inside.
There were a few people inside and two or three waiting in line to order at the counter. Given that they were still one hour to close, I was pretty angry to be turned away with no explanation, especially as that neighborhood isn't so inviting at night. I ended up at Herbivore about a 15-minute walk down the road.
Make sure to call ahead to see that this place will let you in.
