I love In-N-Out so much. Months before this San Francisco trip I was already very much looking forward to having a cheeseburger, fries, and chocolate shake. I figured I might as well go all out...
Cheeseburger $2.15, chocolate shake $1.95. As much as I like Shake Shack's cheeseburger, I think In-N-Out's is better. The meat is so juicy and full of flavor. I wish I'd requested grilled onions instead of raw onions though, as I felt sorry for the people I talked to for the rest of the day. The milkshake-- made of 100% ice cream and thus thick and very chocolate-y... delicious.
Animal-Style Fries from the not-so-secret menu (fries with thousand island sauce, chopped up grilled onions, cheese)

Full list of the many, many locations (all West Coast).
I'm impatiently waiting for the day In-N-Out comes to New York.
