This is by far the busiest In-N-Out in Las Vegas due to its location. Even with the large influx of people, they do a great job of still working efficiently and hard to get everyone their food in a timely manner. There are other locations around the valley if you want to avoid the long lines, but if you want to avoid the long lines at this location, definitely come late night, past 11PM. The lines are almost nonexistent, and they do a great job at getting everyone's food. I love In-N-Out in their entirety and I get my standard 3x0 with both onions, ketchup and mustard instead with pickles, and an order of well done fries. They do it right, and continue to do so.
