Mark and Donnie might have bigger names, but Paul is the star of Wahlburgers.

The Wahlberg brothers opened the restaurant chain in 2011, with the first location in Hingham, Massachusetts — an hour from the Wahlbergs’ hometown of Boston. The chain now has multiple locations in Massachusetts, Las Vegas, and Philadelphia, and one in Coney Island. But as Business Insider reported, the chain will expand to 118 locations in the next five to seven years. The original location earns $5 million in sales annually.
