The Restaurant Chain That Helped Popularize Chicago's Iconic Hot Dog Style - Tasting Table
Briefly

Portillo's is a key player in the Chicago-style hot dog scene, known for its all-beef hot dog topped with classic condiments like mustard and relish. Founded in 1963, Portillo's began as a modest food trailer and has since grown to over 70 locations, making Chicago-style cuisine widely available. With a balanced mix of tourists and locals patronizing the restaurant, its influence continues to shape the city’s culinary identity. Portillo's emphasizes that while they did not create the Chicago dog, they refined the recipe, contributing significantly to its fame.
Brad Fithian, Portillo's assistant general manager, shares, "The Chicago-style hot dog did not originate from Portillo's. The recipe already existed; we perfected it."
Portillo's has expanded from a single trailer in 1963 to over 70 locations, making the Chicago dog accessible to foodies across several states.
