Pumpers: An Adult Burger Store, which originated as a St. Mary's Strip popup, has gained a solid following for its brick-and-mortar location even though it's still running in soft-opening capacity. The restaurant, located at 1101 Broadway near the San Antonio Museum of Art, now plans a massive grand-opening celebration for Sunday, Jan. 19, according to its owners. The shindig will get underway at 2 p.m. and last until the last burger flip at the stroke of midnight.
