"Tucked into the ground floor of a small building in downtown Clayton, St. Louis Rearn Thai provides big doses of authentic Thai flavor. The menu runs the expected gamut: soups, curries and stir-fries. A bowl of tangy thom kha soup is a welcome treat in either hot or cold weather; the red curry is especially terrific, its blend of sweet, savory, salty, sour and (if you ask for it) heat perfectly balanced. The pad-heavy lunch menu is popular with Clayton office dwellers, and after one of the restaurant's powerful Thai iced coffees, you might find yourself with a new favorite coffeehouse" - Riverfront Times
