Here is another recommended Thai noodle place in Pittsburgh, besides Noodlehead. There are many kinds of Thai noodle and rice dishes. My favorite ones are "Yen Ta Fo" and "Toon". The broth of "Toon" is similar to the beef soup at Noodlehead. They have the love boat noodle as well, but I haven't tried it yet. Besides Thai noodles, the restaurant also offers some Japanese noodle dishes. The price of noodles is around $10.5.
For appetizers, I recommend steamed dumpling and "shrimp wrap noodle". I would say that the taste of steamed dumpling here is almost the same as that in Thailand. And I really love "shrimp wrap noodle". It brought me back to the time when I was a little kid. I loved to have a deep fried hot dog wrapped with egg noodles.
