I'm going to be in Montreal in a couple weeks with my gf for a few days and was wondering where to go for excellent sushi. I'd be looking for something a little more upscale, not necessarily in decor, but in variety and quality of fish. We will be staying near McGill, but are willing to travel for good sushi. Price range need not be high, but have no problem paying for good quality. For a point of reference, we are not experts but have had wonderful meals at: Hiro Sushi in T.O., Nobu in New York, and Shige in Halifax. thanks very much for any advice you can offer.
