The best restaurants serving American food in Llangyfelach Swansea South Wales

Called to J47 M4 McDonalds. How this place is still going, I do not know. This had to be THE most disgusting chicken burger I have ever tasted. It was squashed. It was a child sized portion (and I don't have a big appetite!!) And the chips were not cooked, still hard. It was all tasteless, dry, carboard-like and if I hadn't eaten for 6 hours, I would have probably just put it in the bin.
