Shanghai Bao Kitchen opened for business last week just outside the main Dining Terrace at Westfield Montgomery Mall. This is a new venture from three young brothers whose family owns the Rockville restaurant Bob’s Shanghai 66. Dumplings and steamed buns are the focus here, as you’d expect — but we were surprised by the Cava-like assembly line of fresh Asian vegetables, as well as the willingness of servers to recommend which sauces would best complement them. With Chloe’s Deli next door and Korean B/Bop/Q slated to open just across the hall, this new section of the Dining Terrace is turning into an unexpectedly interesting showcase for ethnic foods from local entrepreneurs.
