Burger Boy to open 5th San Antonio restaurant on South Side Newest location to open in the summer on South New Braunfels Avenue Published: Tags: SAN ANTONIO – One of San Antonio’s favorite burger joints is coming to the South Side. Burger Boy on Wednesday confirmed that it will open a fifth location this summer at 4402 S. New Braunfels Ave. The existing building will be fully demolished and a ground-up building that replicates the design of the Shaenfield/ Loop 1604 location will be constructed. “Since the announcement of our third location two years ago, our social media fan base has been calling for a Burger Boy on the Southside,” Burger Boy co-owner Bryce Pohlmeier said. “Well, we heard them, and we’re excited to make our way there and be a part of the community.”
