Food in Britain is fine. we had an empire once and many of its former inhabitants live here! You can eat trad English fare, fantastic Indian, Thai, Chinese, Caribean. Plus food from all ocver Europe and of course the Americas. All this in almost every UK city.
I've sampled French Cuisine a few times. Every time I was dissapointed. I expected culinary excellence and got culinary excrement. Maybe I was unlucky but its happened more than once to be just a one off.
