I love the co-op overall, but I especially love their deli and bakery.
They have vegan baked goods and to-go food, as well as vegan hot food. I was surprised to find a variety of vegan pizzas available to order, and then I was floored to find they also have gluten-free options! Common Ground is the only place I've ever been able to have a vegan gluten-free pizza, and it was delicious -- packed with a nice variety of veggies!
My only gripe is that the pizzas are thin crust and probably 14" (I didn't measure) and run about $15 after tax, which is a bit pricey.
Cons: Price slightly high
