They come two by two, sometimes solo, or in fours, key card in hand, to the small room on the 10th floor of Hotel 3232. Some know what to expect, but others are in for a surprise.

One couple came on their anniversary, a gift from husband to wife, and riding up in the elevator she wondered if he was taking her to a sex party. She was relieved to find that where the bed would normally be was a sushi bar — and behind it the exuberant, wisecracking chef David Bouhadana.

Sushi by Bou Suite 1001 — Mr. Bouhadana’s latest project and part of his growing line of dining experiences — opened in December. It is a speakeasy like no other. New Yorkers love a hideaway or secret place and this one in NoMad has never quite been done before.

Mr. Bouhadana, with the help of investors Michael Sinensky and Erika London, has partnered with the 32nd Street hotel to install a four-person sushi counter in one of its rooms. He is there every night, making his creations, from 5 p.m. to midnight, bouncing to disco music and encouraging diners to drink deeply from the Mr. Sake machine. Each 17-course meal lasts 60 minutes and costs $125 (not including sake), reasonably cheap by New York omakase standards.
