Jersey Mike's is expected to open its doors at 17220 RM 620, Ste. 120, Round Rock, in September. The New Jersey-based sandwich shop first opened in 1956, according to the company website, and began franchising when current owner Peter Cancro purchased the business at 17 years old in the 1970s. With more than 2,000 locations across the country, this will be the sandwich shop's third location in Round Rock. www.jerseymikes.com
