Mikey's Place (aka "The Heart of the Arena") - S2.E13

Mikey opens a Kappa Mikey-themed restaurant, which does lousy until Gonard starts preparing dishes for it. A rival restaurant nabs Gonard and hypnotizes him into making dishes for them instead. In the subplot, Lily is caught showing hatred toward babies, so Ozu forces her to take care of a baby for one day to regain LilyMu’s reputation.
