In his latest No Reservations - "Heartland" (rerun 2 am, Thur at 9, Friday 1 am, next Monday at 7) he starts off in Ann Arbor (probably from his talk at the Michigan Theater- great discussion) and gives it major props, before featuring a chef in Livonia. Of course, on the other hand, he goes to Columbus...but even the Ohio guy with him thinks of Columbus as a cultural wasteland. He hits other cities too, but of note, gives compliments to college students growing standards of taste when heading to Austin.
FWIW. Michigan doesn't seem inclined to get re-involved.
