Why do many Americans think British food is awful?

Why do many Americans think British food is awful? It may be that they have tasted one of PizzaPizza's pizzas in Calgary before flying east. Sitting by the side of the river (try the Inside Out Experience there), Rockies to the west, crisp blue skies overhead, wedges of PizzaPizza's pizza in plates and a bottle of Canadian Rose wine shimmering in glasses. Ummmmm! Yummy yummy. And yes, boys and girls, we DO have wineries in Canada.

And proper cheese. And it's nice too.

In fact, I really like Canada and Canadians TBH. It is my genuine wish to live either there or in Spain in my later years. Preferably Montreal but anywhere considered.
