At the original fancy burger restaurant on the Strip, chef Hubert Keller encourages diners to get creative. Everyone starts with patty options that range from Angus beef to lamb to buffalo, then diners pile on toppings, from the usual bacon and cheddar cheese to the extravagant, like foie gras, truffle mayo, or jalapeno bacon. Be careful though, enough of those high-ticket items, plus the cost of a side of fries, and you might be wondering why you didn’t just go out for a steak instead. If you feel like leaving it up to the experts, there are “pre-determined” burgers as well, like the Keller special made with buffalo, caramelized onions, baby spinach, and blue cheese, or the Hangover Burger; which will remind you of a certain fast food burger that also has special sauce, lettuce, and cheese on a sesame seed bun—but this one is way better.
