I just want to say, that anytime I am at a location in California or Nevada where there is an In-N-Out Burger, I am there at least once. The burgers are just perfect and the wash down perfectly with a milkshake.
I don't know what it is, but a double-double, fries, and a milkshake are the perfect meal. The meat is juicy, the cheese is just melted over the hamburger, and the vegetables are fresh.
The potatoes are cut into fries just before the are put in the fryer. Nothing frozen here.
If you are in California or Western Nevada, find an In-N-Out Burger and try it out.
