We have visited this particular MOD multiple times and always come away happy. If you specify that you are gluten free because of medical reasons they will take good care of you. Even with long lines and during busy times of the day cross-contamination hasn't been an issue. If you are very sensitive it's probably not the best choice, but at a sensitivity of >=20 ppm it's a great place to get some pizza!
I've eaten there several times recently. I've never been sick, the food tastes great and isn't greasy. A pretty good gluten free menu. They have gluten free soy sauce to bring out to you if you want more soy sauce in your meal. They cook your food separately. As with anywhere Just be sure when you order to let them know you have celiac or I find just saying a gluten allergy is much easier.
I can't say enough great things about this place! Chef came out immediately with a notepad to discuss my options and checked on me a few times after my food came out. It was amazing! And no symptoms the next day! The chefs are amazingly accommodating. Just ask to talk to one.
I was and am still a huge fan of this restaurant before and after my diagnosis. The owner is by far the most kind and accommodating person. They recently started offering gluten free pita bread so I think they are still learning what it takes to be considered gluten free. I will need to confirm before I order again that they do not allow cross contamination during prep in the kitchen.
