Wow! This place is great! The owner responded to my email asking what was GF right away and stated that all their pho was GF naturally, as were the summer rolls without the peanut sauce. They said the proteins used for the noodles, rice, or salad bowls was marinated with gluten, so avoid those.
The pho was EXCELLENT. Very fresh, easy to order, and delicious!
Update: I've heard from others that the chicken pho needs to be requested to leave out the fried onions to be GF. I'm vegetarian so it's never affected me, but be aware!
