Texas-based United Supermarkets has restricted its store locations to its home state, and its upscale offshoot, Market Street, only operates 10 stores in total. Fortunately for us, six of those are in North Texas. Market Street’s concept is to mix the supply of a traditional supermarket with specialty items, gourmet foods, and prepared cuisine, so you can shop for school lunches and upscale dinner parties all at the same time.
