This is the restaurant to visit in Montreal when you're a tourist with exchange-rate friendly money to burn. I ate here a few times before I became a vegetarian, and I'd probably go back now that I'm a big meat-eating cheater, because the steaks are excellent, as is the ambiance. It's in a historic building, which the designers incorporated into the restaurant, so it has that old world charm you came to Montreal for in the first place. If you're a local and you're reading this, you probably prefer going elsewhere. Please email me a list of your favorites, because I love your city.
Gibby's, I gather, is something of an institution which means something of a tourist trap, but it's not an overrated, Times Square-esque tourist trap, so I'd say it's worth a visit before you move on to whatever secret hole in the wall your French-speaking cousin wants to drag you to instead.
