What reviewers say
Cocktails and a French spy-themed décor create the centerpiece, with bartenders narrating secret codes and offering off-menu options to curious guests. Knowledgeable staff and canal-side views earn consistent praise, though private events have disrupted reservations and service occasionally slows when redeeming promotional offers.
