Two new sushi spots are heading our way for summer. Suki Hana is just about to open at Westfield Montgomery mall, taking over the long-closed Sarku Sushi kiosk at the center of the Dining Terrace. And just off Rockville Pike, Sushi Toro is moving into the former Hiro Sushi space next to The Big Greek Cafe. Co-owner Andy Qiu, who also operates a couple of noodle houses in northern Virginia, says he hopes to be open by the end of June.
