On the 11th floor of the St. Regis Chicago, Lettuce Entertain You's Miru pairs contemporary Japanese cooking with floor-to-ceiling views of the river and Lake Michigan — chef Hisanobu Osaka (ex-Morimoto, Daniel) runs sushi and refined Japanese plates in a glossy high-rise room. As much about the vista as the fish, but the kitchen has real pedigree. Come for sushi with one of the best dining-room views in the city.
