Even blasé Soho-ites were a little bemused when this space-age shop opened, serving nothing but rice pudding in flavors that sounded like bad names: Subborn Banana, Black Cherry Birthday Suit, Coconut Coma. But the orange plastic take-out bowls are groovy (and reusable), the puddings are tasty, and the place is open till midnight on the weekends. Oh, how sweet it is.
