Summer calls for nights out on the patio with a good glass of wine. Relax and unwind at some of the best wine bars in Las Vegas where you can find a breadth of selections and a patio suited for conversation. Here are the Haute 5 wine bars in Sin City.

The Grape Vegas
Grape Vegas is the type of place equally suited for a romantic encounter or a get-together with friends. The patio overlooking the main gathering spot for Town Square’s restaurants offers plenty of people watching, while the wine list divides its selections by varietal.

We like pairing our wines with the tapas-style plates of sliders, hummus, bruschetta and paté. You can find live music Tuesdays through Saturdays.

Grape Street Café Wine Bar & Cellar
This little treasure tucked away off Buffalo Drive and West Lake Mead Boulevard looks like a wine cellar with its exposed brick walls and concrete floor. You may think you’ve stepped out of Las Vegas and into Napa Valley. Slip onto the patio for a glass of one of the 75 to 90 wines served up individually. Pair your wine with the Mediterranean fare or try it with the chocolate fondue. When you can’t decide what to drink, go for a flight.

Hostile Grape
Travel to Italy, France, Spain, South Africa, Germany and back to the United States with the 160 wines by the glass at the Hostile Grape at the M Resort. This wine bar designed to look like a contemporary cellar features an innovative dispensing system that uses pre-paid tasting cards so you can try as many or pour as much wine as you like. The oenophiles will appreciate the selection of boutique wines while novices can try their luck with different samples until they find one they love.

Nora’s Wine Bar & Osteria
Pair your night out on the patio with fine Sicilian and Italian foods and a glass of wine at Nora’s Wine Bar & Osteria. While the list itself covers more than 350 bottles of wine, you can sample 60 wines by the glass kept fresh with the restaurant’s Enomatic dispensing system. Sample an array of wines by the glass from the extensive flight menu, where similar wines are paired together.

Marche Bacchus

This place isn’t for the feint of heart. Weave your way through the 950 bottles of wine available in the wine store and make your way onto the patio overlooking Lake Jacqueline. Expect to find French bistro fare to go with your wine. Stop in on Saturdays for free wine tastings and Wednesdays and Fridays for jazz.
