Guillaume and Brook Hazael-Massieux are spreading their wings. The owners of the legendary La Becasse (“the woodcock”) French country restaurant in Burdickville are humming this week into their second nest at 118 Cass Street in downtown Traverse City named Bistro Foufou (“hummingbird”). Their new eatery is the fruit of a three-year process that finally ripened last winter when they negotiated the purchase of Hanna Bistro, a prime location just a block off Front St. in the busy center of Traverse City.
