At Zengo in New York City, the Valentine’s Day Dinner and Live Jazz Band (the four-course prix fixe menu is $75 per person) features That’s the Bombe, a dessert prepared tableside. It combines a chocolate sphere filled with bananas, mixed berries, dulce de leche ice cream, pineapple sorbet, cream cheese mousse, almond cookie crumbs, caramel, vanilla and raspberry sauce.
