Seriously. LA is a rip when it comes to booze. I'm pretty sure that Public School 612 has Craftsman for $6 (regular hours), but I could definitely get in on a pizza and $4 delights at Urbanos. Not 100% that I could make happy hour, though. My day off was not meant to be, but I might take a half day and still get there early (4ish).
Just let me know. I'm only about a 10 minute walk from Urbano anyway.
