Keystone in Elkader is open again! Their sandwiches are amazing and it is hard to choose what one to try first. The "Keystone" burger is a must. Choices in seating makes the dining experience fun: bar area, small and large group rooms, and my favorite- the patio over looking the Turkey River and the historic Keystone bridge. Eating at their Sunday buffet on the patio is a nice way to spend a relaxing morning.
