During my many biz trips to Detroit in the 1980s and 1990s, there were basically two fine dining restaurants left in downtown - The London Chop House and, across the street, the Caucus Club. Both closed in the early 90s due to the descent of Detroit but reopened a few years ago. A man would not have thought of having dinner at either without a suit, a lady would be dressed to the nines. Both are probably trying to re-create a world that no longer exists.
