Like a bad elementary school joke, Yocco’s, the Lehigh Valley’s “Hot Dog King,” is serious about its wieners. And these aren’t your ordinary wieners. Since 1922, Yocco’s has been dishing up dogs—cooked Texas-style, served on a bed of chopped onions, and lathered in heavy-duty mustard and a liberal application of “secret” chili sauce—to adoring fans. The now-chain began as a single shop at 625 Liberty Street, and was founded by the brother of former Chrysler CEO Lee Iacocca. (“Yocco” is locals’ mispronounced version of the family’s last name.) Beyond its famous tubes of mystery meat—actually shipped worldwide—Yocco’s also serves the standard fare of hamburgers, cheeseburgers and cheesesteaks, seven days a week. A truly decadent culinary experience… just don’t forget to pack a roll of Tums for the car ride home. (Open M-Th 10a-10p; F-Sa 10a-11p; Su 11a-10p.)
