San Antonio Italian mainstay Guillermo’s will reopen its Government Hill location Wednesday with a new name and improved recipes, according to its owner. Guillermo’s — which also operates a flagship downtown location — closed its satellite eatery at 1216 Austin St. in September to “reset and relaunch” it. Now, it’s scheduled to reopen as Austin Street by Guillermo’s will boast improvements to select recipes, such as the pizza dough, owner Guillermo Garza said in an emailed statement.
