I'm not sure if this restaurant is related to the Bangkok Thai in Savoy, but I think this location on Green St. in Campustown is a lot better than the Savoy location. This is located in the little plaza on Green and Fifth. You place your order at the window and in about 5 minutes, they call out your order and you go pick it up. So there's no waiter service. I ordered the Pho with rare flank steak and it was the most authentic I've had in the area. Yes, it beats out Xinh Xinh by a LONG SHOT. I also ordered an egg roll --- it wasn't great but it hits the spot if you need an egg roll fix. It's more like a Chinese egg roll than those fried Vietnamese spring rolls which I was hoping that this was.... but alas. The soup on the other hand, was delicious. The noodles were the right texture, the beef was tender (although I wish they put more in) and the accompanying bean sprouts, jalapeno, lime made everything taste better!! I love this place and will definitely be back now that I know that there is close-to authentic pho in Champaign now.
They do have an extensive Thai menu as well, but I would stick with the Pho. I saw lots of other customers who had various Thai noodle dishes who seemed happy. The only drawback to this place is that it is in Campustown.
