Wine Cellar & Tasting Room, Las Vegas

It's hard to imagine what 10 million dollars looks like. Luckily, visitors to The Wine Cellar and Tasting Room don't have to—they can just take a gander at the inventory, which includes upwards of 10,000 of the world's rarest and and most renowned varietals. The collection is valued at more than 10 million bucks, but it's not the only reason to visit. Atmosphere also plays a factor. According to Las Vegas Weekly, the vibe is that of "a drinkable museum," where "wandering the cellar... feels like visiting an ancient castle, minus the dust."

Once guests settle into one of the stately stone-and-tile tasting rooms, they can sample wines in multiple ways. There are more than 100 wines served by the glass, plus wine and cheese pairings and up to 30 unique flights available daily. Groups gather around barrel tables by the bar, while couples cozy up on leather couches, sharing sips and flirtatiously feeding each other leftover corks.
