Like all of the In n Outs: Friendly well trained staff. Clean for how busy they always are. Consistent. good, fresh, fast food at value prices. why would anyone eat at Micky Ds or the King?
I just wish they had some healthier options like chicken/vegi, but I guess they only do a few things, and do them well. It's better than a place with dozens of things on the menu all done badly.
Tip: Google their secret menu.
