Surprisingly, I got asked the question a lot when I came back from our trip.
What can I say, English food isn't the best tasting in the world (in my opinion anyways), and you certainly don't go there for the food, like you would, say Paris.
On our trip, wee had bangers and mash, fish and chips, Yorkshire pudding. And good old English breakfasts.
Anyways, I decided to dig up some references on British Cuisine.
