McRib!!!
Food of the gods! I even grab the chipotle 1/3 lb'er every now and then becasue it's a poor facsilime of it. Besides the difference in meat, it's similar that there are pickles, onions, and the BBq sauce...the only difference is the Chipotle is the same sauce with a little more spice. It's not the same, but it works in a pinch!
