The Potomac Pizza/Potomac Village Deli chain is calling it quits on The Kentlands. Doors will close June 18th at the 18-year-old restaurant, which converted from pizza to deli fare just last year. “We made some mistakes, including having two pizza places so close together in The Kentlands and Rockville,” says co-owner Adam Greenberg. “We thought that having a breakfast/deli-type concept out there would be awesome, and our regulars all thought it was great, but obviously the other people didn’t.” The Potomac Pizza restaurants in Rockville, Chevy Chase and Potomac Village will not be affected by the closing, Greenberg says, and a new location planned for College Park is still scheduled to open in August. He says the company plans to continue its deli catering business.
