Sorry, i couldn't find one.
It's weird because I got to the menu via a link at the bottom of this page on the English-language site:
https://centrebell.ca/en/quick-serve so I would have expected the menu to be in English. But basically the gist is:
The burger place has veggie burgers and GF buns
The hot dog place has veggie dogs and everything is available GF except the Bao Dog
The sushi place has veggie sushi options
The Mediterranean place (CHOPA) has a veggie option and also hummus
The pizza place has veggie pizzas and a GF crust option
Most places have a vegetarian poutin option and the three Habs places also have a GF poutin option (because Montreal)
That's not really true - see above - although I did LOL when I saw them listing Lay's potato chips as a GF choice.
