307 Exchange Place, New Orleans, LA 70130
Their regular menu is marked with what options are GF and also vegan and vegetarian options. I ordered the truffle and manchego cheese grits and the uppatan - both delicious. Small place, friendly staff. A filling lunch for less than $20!

This is a bar/restaurant that is best known for their pizza, but they also have an amazing menu including many GF items (no GF pizza though). Their risottos are all GF, and they have many meaty (venison! lamb!) and vegetarian options (avocado! carrot!). The regular menu is marked so you can tell what is GF.

The dough is probably frozen, but it's decent. They have a good selection of toppings to make your own pizza. I've only ever ordered online for delivery and it automatically gives you the special price for a medium (the only size for GF). I'm sure there is a potential for cross-contamination with the sauce/toppings, but I've never had a problem with it.

Dedicated GF and vegetarian menu. I got the grilled veggie street tacos and they were great. My (non-GF) friends got burritos and were also very pleased. All of the chips, salsas, and sides were tasty. Wait staff was friendly and prompt. Clientele seemed to be mostly locals - always a good sign!
