I recently discovered a tasty mystery in New York City’s East Village neighborhood. When you enter Surprise Scoop  it’s quickly obvious that this ice cream shop isn’t like the others. There are no employees in sight and no ice cream is visible in the store, which consists of just a room with two electronic kiosks and a pickup window.

Shoppers have just one choice on the menu: a $10 double scoop of ice cream. Customers order at the kiosk and don’t know what flavor they’re getting, or what the available options are.

When the ice cream is ready, a computerized voice on a speaker calls out the name on the order, the small window opens, and a barely visible employee places the order on a small ledge before shutting the window again.

The experience is the brainchild of Jackie Luu, a Brooklynite who has been in the ice cream business for nearly a decade. His first shop, Stuffed Ice Cream, sells doughnut ice cream sandwiches and used to occupy Surprise Scoop’s current space before moving to Bensonhurst.
