TripAdvisor named Portillo's the nation's best fast casual restaurant in its annual restaurant rankings, while three other Chicago eateries earned high marks in different categories. Portillo's hot dogs, Italian beef and chocolate cake overtook fast casual juggernauts like Shake Shack, Five Guys and Blaze Pizza. The Purple Pig, Alinea and Bavette's Bar and Boeuf also got nods in the fine dining and everyday dining categories.

The world-renowned Alinea, which has topped the fine dining category several times since it opened, slid to 19th place, while Bavette's Bar and Boeuf was called the 25th-best fine dining restaurant. The Purple Pig took 15th place in the everyday dining category.
