After a decade in Harvard Square, the Japanese noodle restaurant Wagamama closed its doors at 57 JFK St. for good on Sunday, July 9. The London-based restaurant chain shuttered its Harvard Square branch in advance of the upcoming expiration of its ten-year lease. When Wagamama opened in the Square in 2007, it was the restaurant’s second U.S location. The chain now has several Boston locations and one in New York City.
