When this place first opened I was a bit concerned because the level of customer service at ANY store near or inside Metrocenter usually leaves much to be desired. However I must say that IN-N-Out has defied the odds and continues to impress me with the way they run their business. Friendly employees, fresh food, and great service are the reasons I continue to visit there (even though I loathe Metrocenter overall). Think about this; they dispatch a person outside to take orders if the drive thru line is too long to make sure your order gets in and you don't leave frustrated.
Really.
Would ANY other place do that? Not a chance. Also, out of all the times I have been there, they have NEVER gotten my order wrong. I am a bit picky with my food and I never have to worry, I can trust them to get it right the first time. The employees are CLEARLY paid better wages than other burger joints which means something to me as well. They are happy to be there (for the most part) and this is evident in the level of service they provide.
My ONLY, and I mean only critique of this In-N-Out Burger location is the shall we say, interesting, way the drive thru is set up. Series of cones to direct you in and when you get out you are in a parking lot of Burlington Coat Factory with many people (usually) walking in the lot. Other than that, this place is a great place to stop in and grab a burger.
Oh and the inside is constantly being cleaned up and I have not seen a "bad" time to go there. Obviously pretty much always busy, but that is to be expected for the service they provide and the excellent food they make.
