A grocery store with an outstanding beer selection. They have their beers labelled by region (Michigan, West, etc). The breweries from Michigan that bottle, they have covered, but not to the extent of what a beer store would.
Single bottles can be purchased from the back portion of the liquor department. A great way to maximize your tastings without breaking the pocket book.
Prices are right on board with most any place. Their single bottle prices really aren't marked up much. Definitely worth the visit if you are in the Detroit area. Enjoy!
