Last time they announced free yogurt I somehow screwed up the dates around Christmas time so I double confirmed this one with the owner.
From an email:
“Tangysweet, Penn Quarter, will celebrate its grand opening on Thursday, January 8, 2009 by offering complimentary frozen yogurt throughout the day. Tangysweet is open daily from 11am to 11pm.
DC’s original tart frozen yogurt store has set up shop at the corner of 7th St. and E St., NW (675 E St., NW, entrance on 7th) one block from the Verizon Center and will tantalize customers with combinations of its classic, green tea and pomegranate yogurt with the freshest fruit toppings, like raspberries, strawberries, blueberries, as well as, crunchy cereal toppings.”
