Today in fro-yo press releases: Red Mango informs us that their product has been certified gluten-free, and Pinkberry reminds us that by the end of May, delivery will be available at all of its Manhattan stores from noon till 8 p.m. Really, this “Swirls on Wheels” thing is evil genius. Maybe we just have this stuff on the mind after reading about Bruni pounding pints of Häagen Dazs, but you gotta wonder — will Manhattan’s lonely hearts, bummed at having no plans on a Friday night, now be littering dark corners of their apartments with empty Pinkberry cups? How long before we hear: “You’ll never believe it! I ordered all this green-tea fro-yo in order to meet the $10 delivery minimum and ate it all while watching a Degrassi High marathon.” Sure, for plenty of people Pinkberry is a group activity (you know, the types who roll in ten deep and make you wait forever), but chances are this’ll introduce the brand to a whole new customer — the “I don’t want to be seen eating fro-yo because I don’t want people to think I’m worried about my weight” type. Come to think of it, maybe Pinkberry should be the next food available via TiVo.
