Cool vibe, a bit of a walk from campus. Staff is super friendly.
We got the poutine dog (monthly special), a vegan dog prepared mexican style, and fries.
Poutine dog: It was unique, but I probably wouldn't get it again. Maybe gravy on a sausage isn't my thing. If I go back I would try something more standard to judge OSS on its pure sausage merits.
Fries: They were fine.
Vegan dog: very good.
You can get most of the dogs prepared with a vegan sausage. I almost wanted to give this place 5 stars just for that. Allows carnivores and vegetarians to dine together in bliss.
