So I made a reservation on YELP. When we arrived we were told they don't accept reservations. Having received a confirmation didn't convince, whom I believe was the owner, that indeed they appear to do so. Neither did the fact a few tables had "reserved" signs on them.
Other than the reserved-sign tables, I was invited to wait until a table became available.
Needless to say I didn't.
Instead we went to Le Margaux down the street, and had a wonderful dinner there.
I won't be returning to Taza Flores any time soon.
My suggestion is you don't go there either. There are enough good restaurants in Montreal who appreciate their customers business and deserve our patronage. Apparently Taza is not one of these.
