Boston’s most-anticipated fro-yogurterie has announced an opening date. After a year of hype and hypotheses, Pinkberry is making good on the promise to bestow more of its tarty, swirled fro-yo on us, just in time for the November chill. (Do they know how cold it gets here?) The outlet’s second New England address—the first set up shop in Hingham’s Derby Street Shoppes last summer—will take up residence at 286 Newbury Street on October 29th. Can the chain out-treat competition like Korean phenomenon Red Mango, and locally owned BerryLine. Maybe. Rumor has it that this is just the beginning of Pinkberry’s plan for Hub domination.
