IN-N-OUT's Double-Double is fantastic. I usually get it Animal Style (extra sauce, extra grilled onions, pickles). IN-N-OUT also has a (not so) secret menu for those who want something a little different.
Kindly do tell, XDCX.
Please! IN-N-OUT Secret Menu The Animal Style Double-Double is excellent, as I mentioned, and every now and then I'll get an order of Animal Style Fries...but really...the fries are great as is, so I usually don't bother with the Animal Fries.
