If your friend is OK with traveling a little over an hour to Michigan City, IN there is a brand new restaurant called TMIP that is literally on a farm with as much of the food used coming directly from the farm as possible. While the meal is indoors, there is a tour of the farm prior to dinner and sometimes the chefs invite people to sit around a campfire with them after dinner. The food is extremely rustic, but really delicious and interesting as well. Definitely a unique, enjoyable, memorable dining experience.
