CLOSED!!!!! This “modern American bistro” on the main floor of a Southfield office tower offers housemade fare from Great Lakes walleye chowder to sweet potato gnocchi and 48-hour chicken brined and then finished sous vide, thus the time designation. All ingredients are American, although the menu celebrates diversity with a changing list of dishes spotlighting different countries. In keeping with the focus on all-American ingredients, the wine list follows suit. L & D Mon.-Fri., D Sat.
