Noi and Kay Saechia, natives of Thailand, named their daughter, Ploy, which means "little gem." The 45-seat dinning room is loaded with ambience, with ornate, gilded carvings, rich wood paneling and Thai background music. Few places are more welcoming. Enthusiastic servers are gracious and polite. More important, Ploy Thai's food is great. The menu is easy to navigate, even for first-time visitors, with user-friendly pepper graphics indicating spicy foods. Entrees are grouped into categories such as Specialties, Noodles and Vegetarian. Many dishes are named for the predominant flavor - Ginger, Garlic and Green Curry.
