Believe it or not, one of Chicago's finest hot dogs is hiding at luxury hotel Four Seasons. The hotel is still all swank, but the restaurant has a much more relaxed attitude. Seasonal ingredients drive the comfort-heavy menu, which includes dishes like the grass-fed burger with smoked-onion remoulade, Buffalo rock shrimp, and the famed Chicago-style hot dog with "housemade everything." End with shareable sweets like bourbon macarons and brownie bites, or keep the larger-size s'mores with smoked marshmallow and graham cracker ice cream all to yourself. The white-tablecloth vibe may have dropped, but be wary of your wallet—prices tend to add up quickly here.
