They did not have GF soy sauce but offered to have it the next time I visit. If it is GF then it should be MSG free? Right?!
This place offer gluten free food but have to request it because they don't actually have gluten free menu. They offer Because the owner have close friends and regular customer that have gluten sensitivity to celiac. Plus a lot of Thai food are normally naturally gluten free, what makes it not because most restaurant do not cook it like it originally/traditionally should. If you're in the area and love Thai food just order and say gluten free.
