There is a common myth among Americans that British food is not very tasteful. My experiences contradict that myth, to a certain extent, anyway.
American beef is far better than British beef.
I have had beef a couple of times that was tough. I thought I would try it one more time and had a rib eye, one of the tenderest cuts of steak that we can purchase. It was comparable to eating old shoe leather. Even British people who have travelled to America comment on how much better our beef tastes compared to theirs. Besides the bad beef, everything else I have had has been delicious.
