I agree with the other reviews that something's definitely off about this place. While Creperie Bretonne does have a pleasant dining room overlooking the street, the food and service left much to be desired.
I had a buckwheat crepe with ham and cheese. The dish was served with piping hot vegetable cream soup, which (judging from the temperature and texture) was microwaved. The crepe itself was quite strange; the batter for the crepe was sweet and thick - almost like an American pancake. The ham was salty and the cheese was piping hot and liquefied (likely microwaved as well).
The crepe places in Montreal are pretty touristy, but I'd skip this one, which is just plain bad.
