I usually have a general rule when eating in Vegas to not order anything that I would normally have back at home. Well, it was around 9pm and I just happened to be walking nearby In-N-Out at the LINQ and so you know, when you crave something you love, you gotta have it!
I just ordered my usual two cheeseburgers Animal style without lettuce and tomatoes (http://bit.ly/2w4yKZl). Just the way I like it and totally hit the spot for me. I didn't order any fries only because I was craving the burgers at the time.
This location is pretty similar to the San Francisco location at Fisherman's Wharf. There's no drive-thru, but a ton of tables both inside and outside. Plus the prices are inflated since it's literally on the Strip, but still cheaper than Shake Shack, and even White Castle.
Overall, this In-N-Out location is a very welcome addition to the Strip and is another great late night burger option if you're in that area.
