We are frequent customers at The Burger Bar here in Las Vegas at the Mandalay Place

I remember that they allow people to bring in their own wine. I couldn't ever get a straight answer as to what the corkage charge was. We were planning a lunch there instead of deciding to go there because we were in the neighborhood. I planned to bring some wine and my Wife wanted to make sure corkage was allowed. After talking to several people we finally found out that corkage was allowed and there was no fee. My only regret is that I brought some1985 Prieure Lichine and they no longer have lamb burgers. I have always liked the combination of Margaux and lamb. The lamb is still on the web site and it has been replaced with buffalo (bison). I wound up having a kobe burger with provolone, grilled onions and prosciutto. Being able to enjoy a gourmet hamburger with vintage wine is wonderful. I often say that I would rather have a $20 burger there than a $50 steak on the strip.

BTW I have no connection with the restaurant except as a frequent and very satisfied customer
