Since K-On! this is the second slice of life anime that has full on conversations about minor topics of how buns are supposed to be eaten. PLUS it extends to more than 3 episodes!
But yeah, best part of lucky star despite the actual content in the episode would be Lucky Channel :D
I loved the infamous chocolate cornet scene. It appealed directly to my weird sense of humor and set me laughing for a good few minutes. That happened quite a few times while watching it, as it is an anime with no real plot after all.
