I agree, the sound of people eating is like listening to someone shitting, zero appeal. Only watch Muk bang without it.
Fast food, well in the UK here so for me its Toby Carvery, fast food full sundays roast. Get in mah belly.
Someone mention Burger King, this has been a UK company for donkeys years and is wide spread in the UK. Its somewhere i go rarly these days, ditto Mc Ds, although still lover their fillet of fish.
Do fish n chip shops count? British fast food is suprisingly healthy if you take burgers=USA. Pie n mash, Fish stalls etc.
