A new Chinese barbecue spot, Hulu Skewer House, is getting ready to make its debut on Rockville Pike. The restaurant has been under construction since last spring in the onetime Mi Rancho space, next door to Yekta. The menu features skewers of meat and chicken plus sides like fish cakes, rice cakes, pickled carrots, quail eggs and milky buns. Doors will open soon for dine-in and delivery.
