Bellini, the upscale baby-to-teen furniture chain, will close its Rockville Pike store next month after 24 years at the same shopping center. Co-owner Mario Anvari says Rockville’s demographics have changed since the early ’90s, and the baby boom has shifted to Bethesda, Washington and Northern Virginia. With that in mind, Anvari and his partners are looking to reopen their franchised store at a new location in Arlington. “The younger generation who move here for jobs are choosing to live closer to D.C., so we wanted to try an area that’s closer to our customer base,” Anvari says. All bedding and furniture in the Rockville store has been marked down for clearance.
