OK, fact not the best burger in the world. Fact not the best slider in the world. However it is a regional thing. People flock to In-N-Out burger as soon as they land in Vegas not because it's the the best burger but because they grew up with in-n-out and the want the nostalgic feeling from their childhood. Just like many of us go to Chic-Fil-A every time we go to California! Service was friendly, dinning area was clean and the food was hot. If you have never had W/C give it a try you may just like it. If you want a GREAT Burger try the Burger Bar.
