The gluten free menu is VERY limited here but they do have gluten free pho!
The gluten free options here are: Tendon only pho, Meatball pho, Plain pho, and Shrimp spring rolls (i do not know if the peanut sauce contains gluten or not so i advise you to not eat the sauce if you are celiac/super sensitive to gluten)
My boyfriend has celiac disease and had no issues after eating the meatball pho and the shrimp spring rolls without the sauce but always double check with the staff to be safe!
