Clover was a very cute food truck and one of the only good vegan options near MIT. I had the seitan BBQ sandwich, which you have to request to be vegan, and the rosemary french fries- both great, but nothing gourmet. However, the prices are very reasonable and the service is quick. The offerings are a bit limited. Overall, probably your best bet as a vegan in Cambridge.
Cons: Limited, Vegetarian
