I can't believe there is yet another Thai place in Squirrel Hill...but I had to try it. Sukhothai stands up well in comparison to the other Thai establishments! Service was good, the atmosphere was slightly nicer than the others (white tablecloths, excellent presentation of food).
We had:
-fresh rolls (VERY good, especially the flavorful sauce)
-papaya salad (good, but on the limey-side and a slightly small portion for $7)
-dumplings (fine, as dumplings go, but a fantastic sauce elevated these)
-drunken noodles (great flavor; we got the American spice level which wasn't especially spicy to us)
-spicy fried rice (maybe the least exciting entree--nothing wrong with it, just not nearly as good as the noodles) - note: we ordered this Thai hot and it still wasn't overly spicy. The waitress brought out extra spicy sauces for us, which was nice.
Overall: Not the best Thai I've ever had in my life, but a solidly enjoyable experience. I liked it better than the other Thai in Squirrel Hill.
