I gotta say, the advert looked a lot different from the reality: the chicken strips were pouring out of the burger and cheese was dripping temptingly onto the meat, as opposed to the pitiful small slice of cheese pictured above. Finally, the bap in the advert was pert and full of volume. The top bap of my burger looked like it'd given up and died.
False advertising mark out of 10: 6. It did look very different, but still tasted delicious (I had two last week!), so at least it delivered on that front.
