Siam Cafe has become one of my dedicated food haunts, especially for late-night munchies (a girl needs more than Bier Markt pizza and burgers sometimes). The food here will probably not razzle-dazzle you (not that any Chinese restaurant in Cleveland can really hold that distinction), but it's consistent and quite tasty. That said, a number of dishes are excellent: the Pad Thai, the Thai Basil Chicken, the Salt Baked Squid, and my new favorite, the Vietnamese Pork Chops. Moreover, the waitstaff is extremely friendly and courteous.
Siam Cafe is definitely one of the best Chinese restaurants in town, and I certainly prefer it over Li Wah and even Wonton Gourmet (both very inconsistent, and their food doesn't taste particularly fresh or clean to me).
