Now of course, the Detroit Urban Craft Fair is reason enough to make a trip to the city on it's own, but just in case you need more reasons, here are some ways to spend your entire day in Detroit:
FOOD: For an awesome lunch, go to Mudgie's Deli. They use local ingredients whenever possible, and their food is super delicious. They also have really good Michigan-made root beer. Mudgie's is open Saturday 11-9 and Sunday 11-4. Last year's lunch recommendation, still very good: Good Girls Go To Paris Crepes. For dinner, check out Motor City Brewing Works. Fancy pizza and they brew their own beer, some of it with hops from Greenfield Village! I'm not sure what their hours are, but I think they're open pretty late. Last year's dinner recommendation was Slow's BBQ, also very good.
