Modern British can be absolutely superb but sadly we also get a lot of poor quality dishes/foods, a bit like anywhere in the world.
Many of my best meals abroad have been as much around the experience/situation as the food per se. After descending from Illimani in Bolivia we were met at the road head with warm beer and day old cold pizza, that was sublimely delicious.
I have had many superb meals cooked high in the mountains using rudimentary cooking equipment but always good quality natural ingredients.
My worst case of food poisoning, Campylobacter, was from a renown restaurant in Bristol.
