Like a million places, but I'll list ones no one else mentioned: Taco Party. Mas Veggies Taqueria. Veggie Crust. Saus. Nu Cafe.

Also great vegan options at: Union Sq Donuts. Momo n Curry. Oleana. Sofra. Sarma. Koshari Mama. Sweetgreen. Carolicious. Fasika. Moona. Clover. All Star Pizza Bar always has a vegan slice. And the Vietnamese spring rolls at Porter Square Books are beyond.
