ok if not Mexican....
I'd really like to find something within walking distnce of rue de Bluery. Something different...not too fancy. My partner is not into fancy...bu we'd like to go somewhere nice.
Giving an intersection, not just a street name will help us to locate where exactly you are staying.
That being said, you are lucky because we are talking about a short stretch of street. And THAT being said, the immediate area is kind of a dead zone for chow. You can perhaps schlep to Old Montreal, Chinatown, or upwards to Mile End.
You could also try Stash's polish restaurant - in Old Montreal. Great food a great prices. You won't go home hungry or disappointed. If you don't know what to have, order the polish plate which will give you a bit of everything (bigos, pierogi, cabbage rolls)
Mentioned on the other thread is Casa de Mateo, its about a block and a half around the corner from Stash Cafe on St. Francis Xavier - it'll do in a pinch for Mexican - not bad, but not fantastic.
There's Garde-Manger (not Mexican, but a crab shack meets mediterranean kinda place), also on Xavier, who's doing some interesting stuff - call ahead as this place is always full. Also turns into a lounge/club after dining time.
