We ate tonight at Pasa Thai, which opened a few weeks ago and is to my memory the first Thai restaurant in McLean (not Tysons). I am happy to report that the food was quite good. We especially enjoyed the Pottery Shrimp (bean thread noodles infused with a really tasty sauce with grilled shrimp, mushrooms and cabbage) and the Sizzling Siam Beef. Among the Thai standards, the Larb Gai and Pad Thai were very fresh and well-made; the spring rolls were more ordinary, but well-presented. I would say that the food is on par with other Thai restaurants within a few miles such as Pilin, Tara Thai and Neisha Thai. The restaurant is in a small space that has been nicely redone. It is at 1315 Old Chain Bridge Road, just off Dolley Madison Blvd., next to Coyote Amigo in the space that over the years has had a succession of Asian restaurants: Misora, Kotobuki and Tomo Sushi. I hope this one fares better than the others; it is a welcome addition to the dining options in McLean.
