There are exactly 61 roundabouts in the state of Iowa, according to Iowa's state website. All of the ones counted are all "modern" roundabouts that are currently in use around the state. The official count, according to this website, is three for Cedar Falls.
A few months back, we reported that a new restaurant was in the works on Main Street in Cedar Falls. Carter House Market & Café is located right in the heart of Downtown and located right next to the historic Black Hawk Hotel. The two businesses are run by the same people.
