Details surface throughout the meal: wasabi root flown in from Japan every two weeks, reportedly the priciest ingredient on the menu by weight, and amberjack that goes through a days-long dry-aging process before being served with a shallot ponzu sauce. Service is personalized, with the chef and staff engaging directly with the counter over the course of the night.
Michelin awarded O by Brush one star in both the 2024 and 2025 guides.
