This one time I went there and my friend paid the bill on her credit card and then when her credit card bill came they had charged her twice. That was annoying. The beer is a little more expensive than I like, and I would never wait in line.
However, if there's space on the patio and you don't mind paying hte extra, it's one of the best patios downtown for sun exposure, as it has a wide open parking lot across from it instead of a stupid light-blocking building.
But I usually just go to Tortilla Flats, cause if I'm going for beer downtown it's usually during prime time when it's sure to be packed at the Bull.
I can't wait for another summer on hte patios of Cabbagetown though.
