I don't know about a PR agent, but I REALLY like the idea of food that effects the entire party. If SE could give us even so much as one well-rounded dish, I would be very happy along with the rest of Team Toad.
Since everyone in Team Toad are tarus I would like to see an item that gave the party regen, refresh, defense+, HP+ and maybe Store TP or Subtle Blow.
I know it's not "epic food" but when you have a tight knit group like mine (all family in RL) we just want to have fun and food items like these could make our playtime a little easier. Epic food (like red curry and hydra kofte) should be reserved for epic battles.
Party foods should be simple to make - like a pot luck dinner is in real life: everyone brings something to the table to enjoy.
I'm the cook for my team. I make all the food, pet food, and pet jugs we use. It would make me so happy to see more versatile party effect foods in the game. It would save us space, time, and gil.
