Gordon Ramsay's BurGR is a must try dining experience if you are in the Las Vegas area!  I would recommend calling ahead though because the wait time for walk up reservations is ridiculous.... the burgers are good but not waiting an hour and 30 minutes for one.  That being said it is probably, in my opinion, top 3 Burger i've ever tasted in Las Vegas. unlike the line of people wrapped around the casino floor I made a reservation and was shown to a table promptly. Our server was polite, informative, and speedy when it came to initially starting our table.  The wings he recommended are amazing, just the right amount of kick and fit the appetizer bill to a T! (delicious but not overly filling) I went with the Hells Kitchen Burger for my main course, it has to be one of the most flavorful burgers i've had the fortune of tasting! So many different flavors then an delayed heat blast... wow! worth every penny!
