Back in the mid eighties seem to remember the best items where lemon dextrose tablets, rolos and yorkies (always had chinese writing on the wrappers for some reason). There where 4 different menus back then labelled A,B,C and D menu A had Chicken curry and apple flakes but on one ex we got two weeks worth of the same one (D) which had minced beef
Bacon roll and Garibaldis were also much prizes as well, I still have a couple of old hexi stoves hanging about.
