I love the idea of a vegan-friendly Mexican restaurant; I have not seen anything like it other than Chipoltle anywhere else. All other sit-down Mexican restaurants I have been to mean you have to eat nachos without cheese and sour cream - or even without guacamole! That is no fun! Adobe Cafe has vegan cheese and sour cream on stock and does not add dairy to guac. They have an entirely vegetarian menu where most items on it can be made vegan easily and all the staff there are familiar with vegans.
One big but, which is that the food is much better at Chipoltle and when making nachos at home. The food doesn't taste like some other Mexican places. Unfortunately, there are no other real good options other than Chipoltle for vegan Mexican food in the Philly area.
If you crave Mexican food and miss it as a vegan, I would recommend this restaurant to you. If you don't mind Chipoltle or can make great nachos and other Mexican food at home, this may be your best bet.
Cons: Food not great
