Overview

Portillo's began as a small hot dog stand called 'The Dog House' in 1963 and has grown into a beloved Chicago institution. Known for its Chicago-style hot dogs, Italian beef sandwiches, and chocolate cake, this fast-casual restaurant chain maintains long lines at its flagship River North location. The restaurant's nostalgic decor, featuring Chicago memorabilia and a 1930s theme, adds to its appeal. Despite expanding to multiple states, Portillo's remains an essential Chicago food experience for both locals and tourists.
