I had been walking right past this place for years when getting Subway. I never entered because the outside of it is very dark. You can't see inside at all unless you press your face up against the window. I didn't do that because it would be weird if someone was eating their soup on the other side of the window.
I entered with my son, not knowing what to expect. I was a little excited because it was going to be my first Thai experience (not just for food).
As as far as the food goes, they gave us some kind of complementary soup, but it wasn't really for us. We called it Mush Soup. Then we ordered Sesame Chicken with carrots and white rice. Solid performance. I ate my whole plate and half of my son's plate.
The service was fast and friendly and the place is impeccably clean. The menu options don't really fit my palate so it it won't be a regular spot for me, but it might be worth checking out if you're in the area.
