Portillo's in the River North neighborhood has been named the best fast casual restaurant in the US by TripAdvisor. The spot was awarded the Travelers' Choice Award. Here's more:
"Award winners were determined using an algorithm that took into account the quantity and quality of reviews for restaurants around the world, gathered over a 12-month period, TripAdvisor said. The fast casual category was new for the awards this year. The Portillo's at 100 W. Ontario St. beat out other national fast casual stalwarts like Earl of Sandwich based in Las Vegas, Shake Shack based in New York City (it has a branch also in Chicago and Oak Brook), In-N-Out Burger in Los Angeles, and Five Guys based in Orlando (with branches in Chicago and the suburbs)."
