Wimpys I tried once when I was in UK for a conference. Tasted more of pork than beef. Didn't finish it.
I'll take a Big Mac any day.

(Eliza, I think I understand your feelings towards them- That is, I can imagine them. I never had to undergo that meat shortage even at the height of the War; beef was available in cafes although there was rationing at home. Some German friends of ours were in Danzig during and after the war- they remembered the canned dog food which they thought was better than some of the other foods that were available).
