The owner is actually Laotian and is really trying to bring something different to Winston-Salem but unfortunately has had to restrain the menu and boldness somewhat to try to get the bucolic locals on board.
I've eaten Pho as street food in southeast Asia and the restaurant is doing a decent job under trying circumstances to make it happen here. My only condiment complaint is the lack of real Asian chilies instead of the tamer jalapenos offered and would like a few more adventurous options to add to the base soup which is a very good approximation of the real thing. With a few tweaks Pho could easily get to 4 stars but I'm not sure the locals would react favorably.
Soup's is definitely worth a try. Otherwise the downtown W-S food scene, while not bad, is fairly conservative, standard fare.
