Season 1, 2, and 3 each had nemorable episodes.
Season 1 had episode 7 “Review” that had all the chaos in the kitchen when a bunch of orders came in at once.
Season 2 had the Christmas flashback “Seven Fishes” episode with an excellent ensemble cast. My favorite episode in the entire series.
Season 3 had Forks that showed a ton of character development for Richie.
There wasn’t an episode in season 4 that stood out to me. Maybe the wedding episode because of the guest stars.
The show isn’t as good after season 4 as it was after season 1, but it’s still better than the majority of shows on TV and streaming platforms.
