I have NEVER been to an Inn-an-Out that didnt have a serious line. Thats not gonna change.
One reason I never eat at In & Out is because no matter what time of day it is the lines are SOOOOOOO LONG I just dont go!!! I have to say I feel for the cooks they go NON STOP their entire shift over that HOT GRILL!!! I dont know how they do it!!!
