This popular Manhattan and Connecticut chain has opened on Scarsdale’s Popham Road to sling crowd pleasing, Americanized Thai standards in stylishly simple digs. Its walls are decorated with jars and bottles of Thai products (many of which can be found at White Plains’s Kam Sen Asian Market), which are arranged to offer spare, modernist decor. Though summer rolls are traditionally a Vietnamese dish, these greaseless, lettuce-packed “salad rolls” make the ideal alternative to light and cool sushi dinners. At Little Thai, the summer rolls are packed with satisfying crunch and are densely studded with pink, snappy shrimp. The rolls are perfect to dip into coconut sweet peanut sauce, whose spare richness gives this clean dish some base.
