From a frequent Detroit traveler, thanks for all the suggestions.
I'll throw out Wolfgang Puck's in the new MGM Grand Hotel & Casino. The bone-in Ribeye, medium rare, $41 and hands down was the best beef I've had in the Detroit area (this is coming from a Texan

). Service, appetizers, drinks, all were above the norm IMO.
Another vote for Buddy's Pizza--on occasions when I bring my wife and daughter, this is their #1 request.
