Jersey Mike’s Subs, a fast-casual restaurant brand that started on the Jersey Shore in 1956, plans to launch new locations this summer in East Naples and Estero. The Estero shop, scheduled to open by mid-June, will be Jersey Mike’s fifth location in Lee County. A franchisee leased 1,500 square feet of retail space in the Shoppes at University Highlands, 19521 Highland Oaks Drive, Suite 302, at Ben Hill Griffin Parkway and Everblades Parkway. The second Jersey Mike’s in Collier County is targeted to open in July in a 1,482-square-foot unit at Shops at Hammock Cove, 5040 Tamiami Trail E., Suite 200. Additional area franchises are planned for the fast-growing sandwich chain, which has more than 2,500 restaurants open or under development nationwide.
