If you're a fan of adult beverages, you should definitely stop by Bell's Brewery while you're in Kalamazoo. If you're a pizza fan definitely get a pie while in Detroit, they have their own unique style which it's very good, Google for good spots to try. If you're not a pizza fan then if you'll be visiting the Henry Ford Museum then you'll be in Dearborn which has some of the best middle Eastern food in the country, check for your preference but if you just want an adventure I'd recommend Sheeba Restaurant and have them tell you what to order, we went in wanting to order our normal middle Eastern favorites and were very happy when the waiter recommended their specialties instead.
