For me, this would be an easy choice. It would be McDonald's Triple Thick Chocolate Milkshake. Is there anything sadder than hearing the slurp of the last bit of a McD's milkshake mixing with the air at the bottom of the cup as you desperately move the straw to suck every drop? I think I could happily eat nothing else for the rest of my life. I know they are bad for you, but I have to treat myself once in awhile.
In case you weren't sure how bad they are for you, Men's Health magazine recently did an article about the worst fast foods and they named the McDonald’s Large Triple Thick Chocolate Milkshake as the worst milkshake. The article went on to say you would be better off ordering two Quarter Pounders than downing this gut-busting shake. They suggest ordering the reduced-fat ice cream cones as a much, much healthier choice. Sorry. The cones don't compare to the heavenly goodness of the shakes.
Tell me what your one food would be to eat for the rest of your life?
