Pike & Rose, the new “downtown” development slated for Rockville Pike and Montrose Parkway (former site of Toys R Us, Filene’s Basement, etc.) is picking up steam as new tenants climb aboard. Pinstripes, which just made its local debut in Georgetown, is close to finalizing a deal for a second location at Pike & Rose. It will offer a combo of bowling lanes, bocce courts, food, drinks and live music — all in an upscale atmosphere with Jerusalem stone floors and communal outdoor fire pits. Pinstripes also will host weddings, bar mitzvahs and corporate events, says CEO Dale Schwartz. “Each of our locations does about 2,000 parties a year.” But you’ve got plenty of time to plan: Pinstripes is scheduled to open in 2016.
