The meme is funny (it is!) until people take it too literally.

Yes there are things in traditional English cuisine that are atrocious (from difficult times for some of them) but I believe what counts as English food is what you can find in England today.

If you want cheap then you have Indian, Chinese etc in addition to the usual fast food places. Fish and chips is good but you have to let go off your prejudices. The fish is super crispy outside and flaky inside but bland. It's meant to be eaten covered in salt with tartare sauce or your vinegar soaked chips.

True the cheap traditional food can be meh compared to Italy or France. If you want really nice English food you'll have to pay more. Gastro pubs, genuine fancy "British cuisine" restaurants are everywhere but you need to be ready to pay the price.

In addition many other countries also have soso traditional food (I think NL, DK etc according to their own citizens). But the problem obviously is that the UK are more fun to target, because the UK wants to be perceived as a superpower in other aspects as they once were. So yeah let's make fun of their food.
