OMG that sandwich was so good! Honestly i can't remember the last time I had such a great sandwich.
We stopped in here for a mid-day snack without any particular expectations, other than to quell the rumbling in our stomachs. I ordered the Malinche - végé and my wife had the Flautas. The Flautas were very good, crunchy and tasty and all that but the Malinche sandwich, wozers. It was great!
Every aspect of the sandwich fro the bread to the cheese and even the lettuce was terrific. Normally I wait until I've been to a place a couple of times before giving a 5 star review, but this sandwich was 5 stars all on its own.
Additionally, the resto is super quaint and family run. Exactly the type of local spot that you want to support. The family has tried to recreate the feeling from Mexican markets and introduce Montrealers to Mexican fare beyond the taco and burrito and I think that they are really on to something. I'm sure that you'll enjoy a stop at Lupita.
