Gong Cha Turns 20: Free Birthday Boba Bottle Drops Sept. 15
Boston – September 15, 2026 -- Gong cha is marking its 20th anniversary with a free, limited-edition Birthday Boba Bottle for every guest who orders the brand's Birthday Drink on Sept. 15 at participating U.S. locations, while supplies last.
