Literally every part of my experience having gone there 2/3 times was shite; soggy chips, overcrowded and obnoxiously loud, the chicken burger literally is no better than my local fast food joint (and a hell of a lot worse than the slightly upmarket fast food places).
Most of that could be forgiven if the prices were reasonable but they’re not; I seriously struggle to see any redeeming factors or reason for it’s popularity beyond the meme of “cheeky Nando’s”, yet there’s not anything cheeky about it beyond the cheek of what they get away with!
