"We visited nearly two years ago so I don’t know if these are still open and as accommodating.
Mellow Mushroom is near Tulane and had great gf pizza and seemed aware of food sensitivities/contamination issues.
We also ate at the dining hall of the Tulane Hillel. It’s open to the public and very gf friendly and kosher too! We loved it.
My friend who lives in NOLA brought us to a liquor store where made to order sandwiches were prepared. I don’t remember the name but I do remember they were aware of food issues and we ate well and safely.
Sadly, Cafe Du Monde did NOT have anything gf to eat, so we sipped hot cocoa (it was February) while the non gf in our party enjoyed the beignets. I hope they get with the program and can have frozen treats on hand for tourists who want to spend money and enjoy the views!"
