In-n-out is the best fast food burgers anywhere. The custom service is always great and the employees always have a smile on their faces....of course that is what happens when you treat you employees well and pay them a good wage.
If you have never been to an In-n-out you are missing out on the freshest french fries ever, as you enter the drive through you will see huge glass windows where you can see the employees cutting fresh french fries right there. You can also see how cleanly the staff is and not to mention the immaculate kitchen, of course there is never any doubt as to the cleanliness of an In-n-out...as the floors are practically clean enough to eat off of. Of course this is a fast food restaurant and not a five star restaurant, however In-n-Out is the "five star" of fast food restaurants.
Fast food doesn't get any better or fresher than this. I moved to North Carolina back in 2010 and when ever I come back to Vegas for a visit, my first stop is an In-n-Out.
