The Student Food Cooperative
If you prefer the granola scene, the Food-Coop in the old Student Center sells organic and non-preserved sandwiches, salads, bulk nuts and fruit. They also sell a lot of vegetarian products in general.
There also is the Food Co-Op Satellite in the Price Center. Occasionally, yummy food from Sipz (a tasty vegetarian/vegan Asian-fusion restaurant) is served.
Next door to the Food-Coop is the General Store.
