A Which Wich sandwich restaurant is scheduled to open around the first week of August at 16212 Impact Way, Pflugerville. The custom sandwich chain will be inside of a new Food Box convenience store that is slated to open at the end of July. Owner Parvez Badarpura, who also owns the Food Box store, said Which Wich will open about a week after the convenience store due to employee training and other matters. Which Wich creates custom and signature sandwiches that include the Meat Balr, the Philly Cheesesteak and the Reuben Wich. www.whichwich.com
