I don't drink beer but they have a very very extensive beer selection. So my beer loving friends love coming to this little place on the Danforth. I really enjoy the atmosphere and the other patrons as well.
One friend hosted a sub-crawl: a pub crawl via the subway, get off at one stop, find a dive, have a drink. Get back on the subway go one stop and repeat! The Only Cafe was one of the stops on this tour and compared to the other "really" dive bars we were at, I found the Only to be one of our better stops! I don't consider it to be a dive.
I would say the prices are fair.
