Udom Thai Restaurant has been serving authentic Thai dishes to Prospect Heights since 2007. Because the cooking aims to be close to what you find in Thailand, dishes tend to be a little spicier. It offers fresh Thai iced tea, too. There's a pleasant bar with exotic cocktails, happy hour and a good selection of beer. Bountiful lunch specials are available Monday through Friday. If you want to order in, Udom offers free delivery.
