It wasn't that long ago, but Muldoon's pizza parlors have faded from local memory. The sign on the front of the Fourth Avenue South shop at left says Muldoon's opened here in 1972. No such clues are on the location at right along U.S. 41 East at the Lely Shopping Center. The shops lasted about 20 years. The downtown Naples site now is Ciao restaurant and the Lely site is a Quiznos.
