SINGLE CHEESEBURGER AT AU CHEVAL IN CHICAGO AND NEW YORK

All that’s griddled is culinary gold at this upscale Chicago diner that evokes the nostalgia of your favorite greasy spoon with the mastery of high-low ingredients. There’s bologna. There’s foie gras.

At Au Cheval, burgers are classified as “sandwiches” on the menu, and in this case for good reason, considering that topping suggestions can be an egg, crispy bacon, or house-made fried bologna for peak indulgence.

THE BAR BURGER AT MAISON DE LA LUZ, NEW ORLEANS

Japanese Wagyu beef is the star of this burger at Bar Marilou inside the Maison de la Luz hotel, located just steps away from New Orleans’ French Quarter. This French-inspired bar, located in a former library, has a menu fully loaded with indulgences—like foie gras with duck prosciutto and a caviar selection—so it’s no surprise that its burger is equally luxe. The Wagyu beef patty comes topped with French Saint Andre cheese—a soft-ripened blend of brie mixed with sour cream and whipped sweet cream—pickled cucumber, lettuce, and onion. It’s served on a fluffy potato bun.

PRIME RIB BURGER AT THE CONTINENTAL, NASHVILLE

Chef Sean Brock’s take is traditional, with high-quality ingredients. The Continental, located inside the Grand Hyatt, just a stone’s throw away from the live music and bars on bustling Broadway, uses quality cuts of prime rib folded into Bear Creek Farm’s ground beef for its burger. The patty is crusted with peppercorns and seared. But that’s just the base of this lavish lunch or dinner—the burger is loaded with red onions, Cantal cheese, tomato, and, the kicker: foie gras mayonnaise. It’s served with gaufrette potato chips and horseradish cream. And talk about a burger that comes with hype—there’s only a limited number of them made every day at the bar starting at 5 p.m. and in order to claim one, guests are given a golden ticket.

The restaurant is inspired by American dining in the 19th and early 20th centuries, and offers table-side cart service.

That’s not all though—it’s served with a barbecue sauce made with single malt Macallan whiskey among other lavish ingredients.
