Was dying for a pad Thai so came for lunch. Siam has a decent Pad Thai, not the best, but definitely far from the worst. I asked for extra spicy and couldn't detect any spice at all. Came with a Tom Yum soup which was also good. The lunch time service is slow however, about 30 minutes to get your food after ordering when the restaurant wasn't very busy. So don't count on getting in and out in less than an hour. A little on the pricey side ($20 for a shrimp pad Thai). Overall a good Upscale a Thai restaurant on the south shore.
