466 Queen Street West, Toronto
Having received varied reactions to me trying KFC's DOUBLE DOWN burger, ranging from "Eeewwww" to the actually curious, "How WAS it?", I have to tell you, I LOVED it!
Yes, it's bacon and cheese sandwiched between two juicy (and incredibly salty) chicken burgers, and at 540 calories, 30 g of fat, and 1,740 mg of sodium (!!!) it's not good for you, BUT it was deeeeeeeelicious and well worth it.
Split between three of us, and no longer available in Canada, I now wish I'd had more of it!
