The Big Mac is made up of "two all beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun" as the jingle goes. The special sauce is McDonald's blend of thousand island dressing.

I still remember when Burger King came up with its version of the Big Mac: the Big King. I've seen Big Mac packaging change from Styrofoam clam shells (which were replaced due to environmental concerns) to a wax paper wrap with a paper ring to help keep the tall shape to its current form in a cardboard clam shell.
Suffice to say, the Big Mac holds a special place in my heart which I indulge every now and again. Especially, when I have a buy one get one free coupon! Otherwise, it's an average price of $3.57 here in the U.S.
True, it's not even close to the best burger I've had, but it's a familiar comfort food that brings back memories and sometimes that's just what you need.
