6 Best Bars in Center Strip, Las Vegas

Leave your designer handbags on the bar; this is a place to see and be seen. Sophisticated clientele frequent this piano lounge, where a different expert each day (check the website and pick your favorite) tickles the ivories of a one-of-a-kind, art deco–style Steinway grand while patrons sup on trendy offerings like the Poof!—a pairing that reflects Las Vegas bars' current fascination with all things smoky, with a cocktail of Bulleit rye, apple brandy, and sweet vermouth, placed under a smoky dome alongside duck confit croquettes. Caviar is, of course, a given, featured in tacos and the Bellagio Martini, served with an Ossetra cigar.

Circles are a big theme at this lounge that fronts Koi restaurant. The motif is repeated in the ceiling and in light patterns projected on the walls, plus the circular banquettes that are great for big groups and lousy for small ones. Be sure to visit during happy hour from 5 to 7 pm, Tuesday through Saturday, when mixologists oblige by offering signature drinks for reasonably discounted prices.

Cigars team up with whiskeys (including barrels and flights) and small bites at this respite in the center of the resort. Find up to 1,000 cigars housed in a climate-controlled humidor, one of the largest in the city. If you're a sports fan, take in the fan cave with its 208-inch video wall and lots of screens. You can bring your own cigars; there's a $10 cutting fee. Become a member for discounts on beverages. There's also a location at Paris Las Vegas.

This baroque Paris piano bar can get loud, but it's all good fun. Free music flows Thursday through Sunday from 7 pm to 2 am; tip the dueling piano players well if you really want to hear your favorite song. Creative cocktails include the Banana Split Martini and Godiva chocolate–based Midnight in Paris, and cigar lovers can enjoy a smoke in the exclusive lounge area.

The Chandelier Bar may be The Cosmopolitan's cocktail-venue claim to fame, but you shouldn't overlook the sleek Vesper Bar, the true mixologist space at the hotel. Name an ingredient, any ingredient, and the talented staff behind the bar can come up with a drink for you. Long-forgotten cocktail recipes are a specialty at this very modern square bar sitting alongside hotel registration.

Different cityscapes ranging from sunset in Hong Kong to night in Dubai to evening in New York City change on huge screens (so you can order a Manhattan while you're looking at Manhattan) that make up the background at this lounge, which offers specialty drinks like a pineapple mule.
