Fair, but in the long run, nothing special tale. The \'twist\' is okay, but not one of the show\'s better ones.
BTW, the episode title is \"Our Cooks a Treasure\", not \"Our Cook\'s Treasure\". The DVD set got this wrong on the box, and on the episode guide on the DVD itself, but the other title is clear as day on the episodes title card. The title also makes a lot more sense considering the plot.
