REVIEW: Sushi By Bou, a speakeasy-style micro-omakase chain known for 12-course chef menus + dining speed, has a new experience in its arsenal. A handful of its 22 locations from Atlanta to Albany have added a monthly Tuna Cutting Experience featuring a 250 lb Bluefin tuna + sliced for a hungry crowd. Susie Davidson Powell joined the guests scraping bones with spoons + drinking sake from its head.
