Nana has always had a spectacular view of Dallas from its 27th-floor perch, but it was blunted by burgundy brothel décor that included acoustic ceiling tiles, brass railings and sagging velvet curtains that cramped the windows. Now more than a year old, Nana's understated makeover has settled in. Alterations include Asian art installations from the Trammell Crow family collection, unobtrusive sage green curtains, rich gold carpeting, newly installed banquettes and ribbed, sandblasted glass panels around the raised open kitchen, subduing the severe visual thrust this culinary cockpit had when it was wrapped in clear glass. The food in this stunning room is virtually flawless, crafted as it is by David McMillan, easily among the top handful of chefs in Dallas. McMillan performs unparalleled wizardry that manifests itself in grilled Texas quail (with armagnac-poached prunes), silky grilled prime fillet in a black shallot sauce and sublime veal Rossini in a brew of Madeira and truffles, among other classics with shrewdly imaginative twists. Service is superb, and the wine portfolio is well-endowed. Plus, there is Nana herself: a 6-foot-by-9-foot portrait of a reclining, Rubenesque nude painted by Russian-Polish artist Gospodin Marcel Gavriel Suchorowsky in 1881. Tasty.
