I went here for a recent Adobe promoted event. Rex's have several beers on tap. I personally tried the Hoegarden...served in the correctly branded glass.
Service was good, the server came around pretty regularly to ask us if we needed anything.
The patio is a decent size as well, with lots of place to move around. The traffic outside the patio is very light...which is definitely a good thing for me, the last thing I need is someone walking by puffing their cigarette while I'm trying to enjoy my plate of ribs.
I would definitely go here again.
