Friends of mine own that place and its really great but call ahead and let them know its your anniversary and you want an appropriate table. The place is tiny and folks are piled on top of each other.
I always go late, so I never had a problem with it being packed, but I can see that happening. My best friend was one of the sous-chefs there until they moved him to exec at Mutiny, I've met the owners a couple of times.
