I am glad to know that Mango's offer a gluten free menu, but they cook strictly w/ peanut oil & for those who have a peanut allergy it can be quite scary. I was there once & didn't see any mention of peanut oil used. I found out from the wait staff & had to leave. Wish I could have stayed & enjoyed a meal, but anaphylaxis isn't what I wanted to deal with.
GF menu and knowledgeable managers. They take care of you if your server is unsure. I have celiac and do just fine there (and I'm pretty sensitive), but I can't promise it would work for all celiacs.
