One of my joys of visiting my in-laws in the Bay Area are the multiple trips to In-n-Out burger. I think it was Katlady who posted the "Secret Menu" a while ago. I had no idea that I could get a 3x2 or 4x4 if I wanted it. I also learned about "Animal Style".
Unlike Paul, I can't handle a well done burger. (or any other meat) I'll risk life and bowel and go with medium and juicy burger.
