This is a Colombian food cart and it is fantastic. Everything is gluten free! It's not very expensive either, nothing is more than $5.

A bit pricey, but delicious. Their gf menu is different from what I've seen before. It gives a list of things to avoid and a list of things that are safe rather than being a typical menu.

They literally have a gf option for every course. Their food is delicious. By far, my favorite pizza place.
