At the risk of resurrecting an old chestnut [forgive that alarming image] this observation is grotesquely anachronistic, and ignores the revolution in British food of the last 15 years. As the quality of British food steadily rises, so that of French food steadily declines. The two trends will soon cross, and in some cases have already done so. (Not to say, of course, that you can't still find bad food here if you're determined to find it, as indeed you can in every country: and we're as much victims to the global blandification of the burger/fast food culture as anywhere else - but there's another side to the story which is very different, very creative, very exciting and very scrumptious).
I still say that steak and kidney pie/pudding is delicious.
