I love Thai Foon. I grab lunch here 1-2 times a month. I always get the spicy basil noodle. It's quite delicious.
For the most part the service is great. On occasion it can be a bit slow depending on who the server of the day is. But I can almost always get in and out, and back to work in a lunch hour. Even on a Friday.
I've never ate there with someone who didn't enjoy what they ordered. Food seems fresh and I keep going back for more.
I tried a few Thai places in San Francisco, and this place of course is Americanized. You're in Pittsburgh, what do you expect? It is worth a visit!
