Took the scenic route out of New Haven today, and spotted Siam Orchids at 899 W. Main (Rt. 1) in Branford, and the Prius just automatically pulled into their parking lot by itself. The roomy dining area is uncluttered with no exotic decorations, and at noon on Saturday only one other table was occupied. I had a short chat with the daughter of the owner as she seated me, and although I hadn't seen the place befoe she said they had been there for several years and had earned a very good rating from the NY Times.
My current craze, the Tom Yum Goong soup came with little mushroom and grape tomato slices floating on top as well as the required shrimp contents. It's spiciness far exceeded the one pepper rating on the menu and I occasionally had to sip some hot Thai tea to cool it off. The yellow curry was also rated at one pepper, but seemed milder than that. (The menu offers you the option to order it up to 4 peppers worth!) It came with what I suspect was unauthentic sweet potato and pineapple chunks, but was good enough that I polished the whole thing off without asking for a doggie bag. The prices are quite reasonable, especially for lunch, so I suspect that Thai's One downtown has a bit of competition.
