I've had fish 'n chips in the U.S. and the U.K. and the U.K. has the better taste-test results for sure. Plus, in the U.K. you always get them with mushy peas, whereas in the U.S. never (or at least not that I've seen). And, you get vinegar with your chips in the U.K. whereas only occasionally in the U.S.
Going back to the U.K. in a couple of weeks; should be a good time!
