Finally some good news to report for the Rockville Town Square dining scene: Tacos and cookies are on the way. Little Miner Taco, a DMV-based food truck-turned-restaurant chain, will open this summer in the former Vie de France space on Maryland Avenue. Little Miner already has a following in Rockville/North Bethesda from its tenure at The Block food hall, which closed last month at Pike & Rose. Elsewhere on Maryland Avenue, cookie chain Dirty Dough just announced plans to take over the long-empty Berry Cup space. The Arizona-based company is known for its multi-layered cookies with gooey insides and flavors that rotate every week. We’re hearing buzz that more new tenants will soon be announced for Rockville Town Square — including a potential successor to the closing Dawson’s Market. (More on that here.)
