This place offers a selection of vegetarian meals, some of which are vegan. I ordered the veggie burger without cheese. It was huge and contained a lot of salad which I liked. However the soy pattie could have done with some flavour, or they could have provided some spicy sauce, mustard etc. The fruit flavoured waters are huge (1L) and good.
They also bring a bowl of spicy pickled veggies to the table, and these were quite tasty and different.
Not the best meal I've had in Mexico, but far from the worse.
Cons: Could do with some spice
