Michael and Asenette Hernandez, owners of Hays Co. Bar-B-Que & Catering Co. at 1612 S. I-35, San Marcos, will open Hays Co. Burgers & BBQ at 17033 San Marcos Hwy., Martindale, in April, Michael said. The new restaurant’s menu will feature old-fashioned burgers as well as barbecue and onion rings. The restaurant will also sell beer and wine. Michael said the “old-fashioned” burgers will feature 100 percent Angus beef on a toasted bun, with toppings, such as dill pickles, onions, lettuce, tomatoes and mustard. Some burgers may also include barbecue, he said. Hays Co. Burgers & BBQ will occupy the building that formerly housed the Cottonseed Café. The property includes outdoor seating and an event center with capacity for about 200 people, Michael said. Hays Co. Bar-B-Que & Catering Co. is also preparing to undergo an expansion that will construct a new, larger building behind the restaurant’s current building and will repave the property’s parking lot. Michael said he anticipates the project taking about seven months. The restaurant will remain open throughout the construction process, except for one or two weeks right before the restaurant moves into the new building. Michael said he anticipates holding a grand opening for the new facility after construction is complete.
