I LOVED my meal here (lawerenceville location)! I asked if the veggie sausage was vegan, the waitress said yes and the proceeded to inform me on what else is vegan.
I got a vegan tofu dog in a wheat bun, Bollywood style (default buns have dairy which is noted on the menu)
A veggie sausage on wheat covered in sauerkraut
The garbanzo bean fries with lemon tahini sauce (VERY lemony)
And a great cocktail (like most restaurants, it's up to you to figure out vegan cocktails with barnivore, they can tell you ingredients in their specialty items though)
Turns out the gravy for poutine is vegan so you could get a vegan poutine with no cheese! (The gravy was delicious, a dining friend ordered it)
