Bao Bei, a Taiwanese restaurant whose owners recently competed on the Food Network, will open its first brick-and-mortar location at Rockville’s Montrose Crossing. Chef/owner Kevin Hsieh launched the business two years ago, working out of a shared commercial kitchen and fulfilling online orders via delivery apps. Hsieh is known for his pork belly bao buns, but he also showcases Taiwanese street food like braised eggs, pickled cabbage and brown sugar swirly buns. Earlier this year, Hsieh and his partners competed on Food Network’s The Great Food Truck Race — and made it all the way to the finals. Now they are back at work in Rockville, where they hope to open Bao Bei this winter between Honey Pig and Kosmo Nail Bar.
