What do "The Corner", "Caleb's Kola", and "U.S. Taco Co." have in common?

As tastes change, food companies try donning hipster guises

Excerpt:

At a taco shop in Southern California, milkshakes are served in mason jars and a chalkboard menu lists "The 1%er" made with lobster meat. The logo is a pink skull and instead of buzzers, customers are given license plates so servers can identify them when bringing out orders. Nowhere is it evident that the U.S. Taco Co. is an outpost of a chain better known for cheesy gut bombs: Taco Bell.
