I would give less than one star if I could.
The fries are not great (taste just like basic Swiss Chalet fries...go to Five Guys a few doors down and the fries are unfortunately substantially better); and the service is so incredibly rude. My partner was snapped at with the most condescending tone by a woman with white/blonde and purple hair, because he didn't speak French. She had such an attitude problem, and my partner is not one to ever complain about anything. He was genuinely shook up by her demeanour. We are in Downtown Montreal, the tourist hub in the whole city...calm down, and recognize that tons of people don't speak French! Rest assured, fellow tourists, most establishments in Montreal are not like this and many people are very kind about the language barrier.
Lastly, for a place that specializes in fries and dipping mayos for said fries, you'd think they would invest in proper packaging with lids? Our takeout order was disgusting with sauce everywhere - ugh!
Do yourself a favour and avoid this place at all costs. There are so many better MTL restaurants around that will offer friendly service and a good product.
