I used to go to Clement Street in San Francisco where you could walk into any little store and order dim sum,pork buns,spring rolls, bbq pork, and other little yummy items and have them packed into a pink bakery box to go. All these items were in the windows of the restaurant/bakery and readily available to all. In most of the places, there might have been 6 or so tables, most of them taken up by the staff. Is there anything like this in the Dallas/Ft. Worth area?
