Laredo-based Tex-Mex chain Taco Palenque is streamlining its San Antonio operations by building a central kitchen to serve its 10 locations dotting the city. The $5 million project will convert an existing 58,000-square-foot warehouse at 8743 TX-151 in Bexar County into a commercial kitchen, according to a state regulatory filing. Restaurant chains often set up central kitchens to advance-prep food for their customer-serving locations.
