Nom Wah Tea Parlor Originally opened in 1920, Nom Wah Tea Parlor is NYC's oldest dim sum parlor and is located in the heart of Chinatown. This throwback gem was recently remodeled, but it retains the old-timey charm that has kept it buzzing for almost a century. Longtime regulars and first-timers enjoy the incredible dim sum and other dishes, such as ha gow (a traditional Chinese dumpling), the Original egg roll (mixed veggies and chicken rolled in an egg crepe, then fried) and traditional pan-fried wheat-flour noodles.
