The Hostile Grape remains the best place to sample a huge array of high end wines in Vegas.
Wine lovers, set a budget and stick to it. It is very easy to spend several hundred dollars especially when you have the chance to sample impossible to get cult wines (I was fortunate enough to sample two vintages of Screaming Eagle).
Service is excellent. All staff members, including the cocktail servers are knowledgeable of the wines offered.
Tasting prices are scaled based on the size of your pour. Prices are in line with most wine bars. Full bottle prices are the best of any Vegas resort property at about full retail. There is even a limited selection of large format bottles.
Stemware is excellent if you order a full bottle.
Great place to chill and talk it up with other wine lovers (not wine snobs, its Vegas after all)!
