CSNY Pizza, the long-awaited spinoff to Rockville favorite Pizza CS, quietly opened for lunch this week at 1020 Rockville Pike. Hours will be expanded in the next week or two, says co-owner Ankur Rajpara, who runs the six-year-old business with partner Jonathan Allen. The pair have a reputation for perfectionism, having traveled to Italy and deeply researched Neapolitan cooking techniques before they launched their first restaurant at Twinbrook Metro Center. The new place, in tighter quarters at Edmonston Crossing, offers New York-style pizza with a focus on takeout and delivery.
