In NYC Chinatown we have a good ole tried and true restaurant called 69 (Bayard street) to go to for tasty post partying Chinese food.
Based on a recent late night experience in Montréal, it sadly seems to be that their equivalent of 69 is a place with horrible service and bland food.
The waiters here are very weird. Never mind that they were ridiculously (size 24 waist) skinny. They provide unfriendly service.
I saw they have a separate menu for Vietnamese food. I inquired about this to the waiter asking if they really served Vietnamese food and he tapped the menu in my hand in an annoyed way like some guy flicking an ant off his picnic table as if to say "duh idiot. What's so weird about a Cantonese restaurant having a separate Viet food menu"?
The seafood pan fried noodle dish here tasted bland with mediocre seafood and noodles that were not very crispy but at least it came with a lot of veggies.
