Best GF Chinese food in the DC area!! They can prepare almost everything with GF soy sauce in a separate wok. I have always felt great after eating there. And the food is awesome!
It is also strictly kosher - so no pork, no shellfish, is closed on Saturdays, and closes 2:30 pm on Friday.
Holy Chow has a lot of choices that can be made gluten-free with gluten-free soy sauce, not just a white sauce. The obviously gluten items (e.g. egg rolls and lo mein) can’t be made gluten-free but they do have gf rice noodles.
