If you like interesting beer, try Get Well. They rotate the taps constantly. And now they are even micro-brewing their own. They've got different casks, and lots of local Ontario brews of all different kinds.
Cool vibe, lots of seats (although that couch in the back worries me. Bed bug paranoia?), and video games! Retro video games! Love the Dolly Parton pinball game. Who knew that even existed outside of Tennessee? It does, and it's awesome.
Great place to go with a group, or alone for a good brew.
