I haven’t found too many quality beer bars in Las Vegas, but Burger Bar in Mandalay Place qualifies.
Burger Bar is literally located in a mall between Mandalay Bay and Luxor so it feels kind of out of place, and the ambiance isn’t exactly beer-nerd chic. But it has a solid beer list with dozens of drafts and even more bottles.
It’s not called Burger Bar for nothing; the burgers (Black Angus, Naturesource or Kobe beef; lamb; buffalo; chicken; salmon; turkey; or veggie) are to die for. You build your own burger monstrosity using dozens of possible toppings, and they have four different kinds of French fries (skinny; fat; sweet potato; and buttermilk zucchini) in addition to a bunch of other greasy shit for sides. Neither the beer nor the food is cheap, but that’s to be expected in a mostly-upscale Vegas bar.
I had a turkey burger with a fried egg on it, a side of skinny fries and a St. Louis Framboise draft, and I was in heaven on The Strip.
The servers didn’t seem particularly knowledgeable about the beer, but they were extremely friendly and attentive, even though the bar was busy when I stopped by.
If you’re looking for bar with an interesting craft beer selection and good eats in Las Vegas, you could definitely do worse than Burger Bar. (Todd English P.U.B. in Aria is also worth a visit.)
