Ugh, really?
As a Brit that’s moved to Australia let me say the kebab shops here are a revelation. The meat is nicely cooked, generally identifiable, and not swimming in grease. The bread is usually more like real Greek gyros bread, the salad fresh…
My memories of Kebabs in the UK is of very dubious slices of something coming off the elephant-leg at the back of the store, nothing you would ever consider when sober.
That's called shwarma and it's some of the most delicious meat known to man. Fun fact, tacos al pastor (possibly the best food of all time) is based on shwarma which Lebanese immigrants brought to Mexico:
