Lou Mitchell's (Chicago, Illinois)
Lou Mitchell's is where many travelers start their trip, and it feels like it. The dining room is always buzzing, with plates of pancakes, eggs, and toast coming out nonstop. You might even get a small box of Milk Duds while you wait, which has become part of the tradition here.
After breakfast, head over to the Route 66 Begin Sign for your kickoff photo. It is just a short walk away and marks the official start of your journey.
