LAS VEGAS (TheStreet) -- Cocktails, a staple of society as a straight spirit or combo, have evolved to maximize the flavor, aphrodisiac power and overall sensuality of the drinking experience. In the latest step in that evolution, nonalcoholic ingredients have moved out of the box from simple syrup to such unusual ingredients as peanut butter and the oyster.

TravelsinTaste went to the city of mixology -- Las Vegas, of course -- to discover cocktails with ingredients that make them strangely sexy, delicious and thirst quenching. Here are our top picks for the social influencer who wants to pique the curiosity of his or her imbibing companion:

Rick Moonen's RM Seafood's Oyster Shooters come in six surprising combinations, including a cucumber-yuzu oyster shooter with cucumber-infused gin, yuzu and orange juice and an Anchor Steam oyster shooter with the namesake draft beer.

The sexiest cocktail on our list is the Bunny Tail, a homage to the original Bunnies' most noted fashion tradition, that's served at the Playboy Club inside the Palms Casino Resort. Created by mixologist Dave Herlong, the drink blends the seductive tastes of Limoncello, San Pellegrino Limonata sparkling soda and a choice of either Ketel One, Ketel Citroen or Don Julio Blanco. The distinguishing feature, though, is that after being garnished with a lemon wedge the Bunny Tail is topped off with a puff of cotton candy -- just like Hef's bunnies, although in this case edible. It is served with the Pellegrino and a minibottle of liqueur on the side, so indulgers can pour the sparkling soda and liqueur over the cotton candy, watching the cotton candy dissolve into the rest of the concoction.

Socialites and bunnies alike can indulge in this sweet concoction, and perhaps might also indulge in Executive Chef Geno Bernardo's Nove Italiano's Spaghetti Nove, one level beneath the club.

For those of you looking for another candylike thirst-quenching option, there's always the Classic Mojito at ROK Vegas with rock candy syrup. The drink also includes Bacardi rum, fresh lime juice, muddled fresh mint and a splash of club soda. ROK recently announced its spring lineup, including interesting fresh fruit and chocolate creations such as the Banana Island and the Mochatini.

One atypical pairing is the Peanut Brittle, a specialty cocktail on the menu at the Luxor hotel. This cocktail is a mixture of Ketel One vodka, Nocello Walnut liqueur, Bailey's Irish Cream, Butterscotch Schnapps, peanut butter, simple syrup and heavy cream, served in a peanut butter-rimmed cocktail glass. Sweet, rich, creamy and, of course, nutty, this is definitely not an all-night cocktail but works great with or for dessert.

For those who want to quench thirst and hunger with a nod to the aphrodisiac, turn to Rick Moonen's RM Seafood for a combination of oyster shooters -- the restaurant serves six with additional surprising ingredients: the cucumber-yuzu oyster shooter with cucumber-infused gin, yuzu and orange juice; the plum-pomegranate oyster shooter garnished with tapioca pears and including Kaku-Rei plum sake and Pearl pomegranate vodka; the bloody mary oyster shooter; the margarita oyster shooter; the dry martini oyster shooter with olive juice; and, for those who just want to down a beer and forget about the hard liquor, the Anchor Steam oyster shooter with the namesake draft beer.

For those who want a little more Zen, head to the tea service at the Tea Lounge in Mandarin Oriental -- along with a Veuve Cliquot Afternoon Tea Experience, it provides a sophisticated boozy take on traditional teas. Don't be fooled; this is not your grandmother's afternoon tea service. (Or maybe it might be!)

Concoctions include the royal tea with Absolut Mandarin, homemade simple syrup, chilled Osmanthus polong tea and a splash of fresh lemon juice; the tea-tini prepared with Bulleit bourbon, chilled Jasmine Pearl tea, apple juice and agave nectar; the kiwi-green tea fizz, a combination of fresh muddled kiwi fruit, homemade ginger simple syrup, Veev acai Liqueur and organic lychee green tea topped with chilled ginger ale; and the signature MO-tea prepared with Stolichnaya Razberi, Amaretto di Saronno, Navan, chilled Introspection tea and freshly muddled raspberries. If the mood strikes, you can grab a bite at MOzen in the hotel. It might be just the munchie one needs before heading off to an evening of gaming!
