This is pretty much always my first stop after picking up my rental car when in Las Vegas. This is probably the busiest location in Las Vegas as it's the closest to the airport and The Strip. They are always busy and there's always a line but they work pretty quickly and efficiently that the wait time isn't too long. There is both indoor and outdoor seating available.
The customer service is always pretty good both inside and at the drive-thru. What I thought was pretty neat was that when you order from the drive-thru, they ask if you'll be eating in your car because they give you paper place mats to put on your lap if you plan to eat in your car. Pretty nifty In-N-Out!
Their menu is simple yet so satisfying. They only offer a few types of burgers but they do the job pretty well. You can also ask for "animal style" burgers or fries, it's their own concoction of a sauce-very similar to Thousand Isle dressing. I've had it but the burgers and fries taste delicious all on their own and you don't really need the dressing.
I love, love, LOVE their french fries because they're freshly cut potatoes. You can actually see the employees behind the counter using their handy-dandy potato slicer. This makes that much of a difference because the fries taste so much better if they haven't been frozen.
I think it's awesome that this location draws so many tourists. Every time I'm here, I feel like I'm at the airport. One, because it's so busy and two because I always see so many tourists and hear all types of accents. There have been numerous times where I'll see a couple with like, 4 burgers and 4 orders of fries just trying to get their In-N-Out fix as they don't have one back home. It's pretty hilarious but totally understandable.
I really wish there was an In-N-Out back home in Hawaii. We desperately need some good quality and low-priced fast food joint like this!
