Ah. NOW I understand what you are talking about.
The restaurant (or microbrewery) have a daily special, which appears in the Item Manager under Food or Booze. If you right-click (or for me, control-click) on that item, the popup menu lets you select "Game Description", but when you select it, it submits "desc_item.php?whichitem=null", which doesn't work.
I spent some time yesterday and discovered that there was nothing whatsoever wrong with KoLmafia's descid for the tofurky nugget. Since I don't - and never will again, I expect - have a character in a Myst sign, it never occurred to me that restaurant items had anything to do with this. But, I can reproduce it with my no-longer-ascending multi who can see that today's micromicrobrewery special is the tequila sunrise...
