The 'Cronut' chef is serving an 8-course dessert, and we've never seen anything like it

Dominique Ansel rose to celebrity chef status when he invented the Cronut - a doughnut-croissant hybrid. People lined up for hours outside his Manhattan bakery just for the chance to taste one.

Now, the pastry chef is doing something even more ambitious. He recently launched U.P., an eight-course tasting menu. It's the equivalent of a fancy dinner, except for one big difference: every course is dessert.

Reservations are hard to come by, since Ansel serves the menu to just eight lucky diners at a time, a few times a week, in the test space above Dominique Ansel Kitchen.

But for anyone with a sweet tooth, it's worth a trip. The menu is currently themed around "firsts," and includes dishes like "first kiss," with roasted peanut water and cream soda pearls, and "first heartbreak," a version of baked Alaska with Valrhona Guanaja bitter almond ice cream and meringue.

The experience is $85 per person, and $45 for the drink pairing. Reservations can be made through the kitchen's website. Thanks to Dominique Ansel's chocolate supplier, Valhrona USA, for hosting us at U.P.
