Opened in 2012, Au Cheval is rated as one of the top new restaurants in Chicago by Chicago Magazine. Great food, great service. Hamburger is awesome, served with two prime beef patties, between a lightly toasted bun. Best burger in Chicago. No contest. Some rank the burger as the best in the country. Reviews from numerous sources, including Bon Appetit, rank the burger as superior. Crispy fries are a perfect complement. We beat the crowds by going on a weekday. Try brunch.
