@SPARKY1922 Just to clarify, you can store food in the yard sale tables and the freshness will last the same as if it was in a fridge. You won't get a list of recipes to choose from or anything like a regular fridge. My R2R Sims store leftover grilled foods, free food from festivals, sack lunches made from leftovers they've 'borrowed' from townies in the park or from platters of bar meals they've bought.
If you've stored any food in there, just remember to take it out before stocking your table during a yard sale or it will be put on the table to be sold. Only takes a second to do though and then you can just put it right back in there. :)
