Stack Burger Bar on West 4th in downtown Austin is part of a nationwide trend toward upscale burger bars with quality beef, and this one truly satisfies, although it’s often very crowded. The burgers were reasonably priced and cooked to order, and the fries were excellent as well. An added pleasure the night I was there was that a Cedar Street Courtyard SXSW party with a DJ was going on in the downstairs courtyard below the restaurant windows.
