I absolutely love the crobster roll from the Canteen. The seafood tastes really fresh and every time I've been there, the servers have been friendly and nice. I've ordered the crobster roll both with the regular bread and the gluten free bun - and I feel like less seafood is given in the gluten free bun (it's a hamburger bun instead of bread slice). Overall, I'd love to come back next time I'm in Dartmouth and I would advise making a reservation beforehand as it's usually quite busy.
