Au Cheval is a burger place in Chicago, and it's one of our highest rated restaurants on The Infatuation's Chicago site. The burger comes with a huge steak knife stuck into the middle of it, so it's very serious. Needless to say, we were excited to hear that the owner of Au Cheval was opening 4 Charles Prime Rib, a West Village restaurant that would be serving a similar burger. The small and dark underground space looks like a robber baron's underground hangout, which is to say we plan on hanging out here regularly. While the burger is good, it's actually the prime rib that arguably steals the show here. There's also a pasta that's both carbonara and cacio e pepe, in case you're attempting to have a heart attack.
