This small coffee shop has it's name right - "Hut". It is located on the south side of Savanna, Illinois. Though it is small, it does have a good variety. There isn't a lot of room to sit inside, but there are two picnic tables outside.
Better yet, get it to go. Then head 1 mile north and enjoy your coffee and the view of the Mississippi River at the same time. Or a couple miles south will put you at the National Wildlife Refuge overlook on the Mississippi River.
