If you lived through the '60s and '70s you recognize this building as originally a Long John Silver's Seafood Shoppe.
It's been many different things since, including a hot dog stand and a Skyline Chili.
Today it is the Cedar Valley Cafe (Lebanese and American) and has been a prosperous business for several years.
The current exterior imagery goes back to the hot dog days.
