The day that Drip Tea ran out of vanilla soft serve for a Tiger Boba sundae was the best day of our lives as we were then forced to have it with their ube soft serve instead. We’ll always order it with ube from now on, because the earthy purple sweet potato combined with a kind-of-nutty brown sugar syrup drizzle and chewy tapioca pearls could totally beat up a hot fudge sundae in a street fight. And, the yam-and-brown-sugar situation gets us excited for Thanksgiving no matter what time of year it is.
