O2 Yoga, which has a studio on Mass. Ave. between Harvard and Central Square (as well as one in Somerville's Spring Hill), has recently opened a vegan cafe, appropriately dubbed O2 Vegan Cafe, at its Cambridge location. It's the only completely vegan cafe in Cambridge, they say.
On the menu: bagels with toppings like homemade Nutella or avocado & tomato, breakfast burritos, sandwiches, salads, smoothies, desserts from FoMu and Sabertooth Vegan Bakery, and more. Pro-tip: put in a pre-order before class and pick it up when you're ready to leave. The cafe is currently open 8am-4pm Saturday through Wednesday and 8am-9pm Thursday and Friday.
