Hey! I watched this one too!
Liked Saffron's design, and I noticed that Minuette and TwinkleShine were in the background in the restaurant.
You know, I know that friendship problems can pile on in a world of emotion eater monsters, and butterfly effect and the Map is basically a seer stone for the will of God and the correct order of the universe, but it still seemed like a stretch for the map to send Rarity and Pinkie just to get a fledgling pony restaurant on it's hooves.
But then in the end they do more than that, they basically discredit Zesty and undo the bland stasis she'd locked Cantorlot's food culture into through intimidation. It still seems like a small thing but I did like the implication that the map senses small problems that can be used to undo larger ones. It seems like a parody to say Zesty represented an dangerous 'friendship threat' but...
A lot a ponies weren't 'following their destinies' because of her. They changed the way they cooked, the way they lived, perhaps others flat out quit, because they couldn't fit in. Given the connection to cutie marks and value the show places on finding one's place, perhaps that represents a danger to one's 'soul' in a way that might not be as obvious as a big horrible monster. Zesty, like Suri, could practically be an "Element of Disharmony" despite being a simple unicorn.
Or it's a send up of Hell's Kitchen style shows. I probably need to get some sleep
