This is not a review of the Tempe In-N-Out Burger but all of them. I do not even begin to understand the craze over this place. You begin with a line that no sane person would actually wait in for a really horrible burger. Then you get through the line and get your burger. The sauce they put on those burgers is so SOUR it affected how everything else tasted and ruined the whole meal. I thought ok, maybe it was just this sandwich. I tried it again, the lines were LONGER because they had been here about a month longer than the month before, and again the WORST meal on the planet. The hamburger has just about enough meat to fill a whole in a cavity in your tooth and the sauce is AWFUL. I will NEVER go here again, even if everyone else in my group is, I'll hie my butt over to Denny's and get a burger with some meat and flavor.
