It's fair to say that some of the wines at the Wine Cellar have more history than Vegas itself. No place for celebrity sightings or picking up dames, instead this no-nonsense bar caters to discriminating taste. Over 45,000 different bottles are on offer, ranging from a 1900 Chateau d'Yequem to Thomas Jefferson's own Madeira Port, and the knowing staff will make sure that you find a taste that you can appreciate. The menu offers samples in "flights" as well as full glasses of the grape, some of which run up to $375 per glass. With a knowing staff and some tasty hors d'oeuvres, this is a perfect place to start off a long evening of decadence. Rio's Wine Cellar and Tasting Room at the Rio All-Suite Casino, 3700 W. Flamingo Rd., 800-752-9746.
