We ordered vegan ramen (we're not vegan - the non-vegan broth has gluten but the vegan broth has no gluten so it's a good starting point) with the gluten free noodles and replaced the tofu with pork belly.
The gluten free noodles were the same type that are used in pho a lot. Those are naturally gluten free as they're made from starch and water and they are DELICIOUS. So everything turned out delicious.
Also - they don't upcharge you for needing gluten free like a bunch of other places do. The gluten free ramen was the cheapest of the ramens on the menu - which is a rare treat.
