What more is there to say about this place, best burger ever, get the secret menu, etc... Cash only, but a lot of the places on Queen West worth going to are like that anyway.
Got the Vatican (burger on two grilled cheese sandwiches) and the beef was incredibly moist and tender, like the premium angus burger at Harvey's but better. People used to dollar menus complain about the price, but when you consider the quality of the beef (much better than any chain) and the added labour of doing a grilled cheese bun, the prices stack up pretty well against the big chains, and you're supporting a Toronto business.
