In-n-out is for sure one of my favorite burger joints! Their use of fresh ingredients is what makes this place so awesome! Not to mention great customer service :) If you haven't been to In-n-out make sure to get yourself a double double and fries animal style, it will change your life.
This location in particular is generally busy as it's right on Nellis and in a busy shopping plaza. Service moves pretty quickly but you should expect some sort of a wait since everything is scratch made and fresh. As always good food takes time!
