Finally found THE go-to place for a quick cheap bite at anytime of the day, on St-Laurent. They open late too!
As a regular customer, I usually go for two burgers- the beef burger and the tofu burger. Both are great. You can choose add-ons on your burger, as the staff will hand you a sheet to mark what you want. The burgers are small but they are inexpensive. Be aware that the buns are ciabatta buns - if you're an avid fan of brioche buns. I've tried the potato fries once and they are great!
Now, the atmosphere of the restaurant. A very "plateau" vibe with good service. Note that the restaurant is very small, but size does not matter here. The customers usually go for a quick meal, but it's always better to take-out.
However, if you do take-out, you might have to wait a while before getting your food. The kitchen is doing what they can to get your food as fast as possible but you will have to wait.
