This year, Dunkin' will be celebrating St. Patrick's Day with a special "O'Dunkin" location in downtown Boston.
On Wednesday, March 6, customers will be able to get free coffee at their 510 Southampton St. location. The first 250 guests to visit between 9 a.m. and 2 p.m. can get a free small hot or iced Irish creme flavored coffee or latte.
The store will be dressed up for the location with special festive decorations inside and out. The occasion marks the start of Dunkin's St. Patrick's Day menu, which includes a mint brownie donut.
