Knapp's Donut Shop is a small bakery that makes all of its donuts, bagels and other baked goods on the premises each day from scratch. The manager, David Lee, calls the establishment "family-friendly." The dining area features diner-like booths and an open view of the baked goods. The business has been running in Rochester for 14 years and has become a spot for many regulars in the community, especially early-morning commuters. It also has a location in Troy, Michigan.
