I'll pile on the food:

Star Deli in Southfield for amazing tuna fish
Steve's Deli in Bloomfield Twp for hot Pastrami
Loui's Pizza in Madison Hts for great pizza and the "Loui's special" sandwich
Millers Bar -another vote for their burger.
Checker Bar downtown Detroit-another great burger
Cameron's Steakhouse in Birminham for, yes, steaks.
Roma cafe in Eastern Market for great Italian.
and last, but not least:
The Lark in West Bloomfield-for the finest dining in the area. And prices to match!
