Mog Garden also has the 'rearing ground' area for the monster-raising mini-game. In itself, it's pretty easy and while similar to chocobo-raising, it's nowhere near as demanding time-wise.
You also can get some very nice bonuses from the various monster 'cheer-effects' (key item.)

EDIT: Also, as a side-benefit, Mog Garden has some side-quests which grant some items...specifically that Super-Mario-esque set of overalls, and the Monkey D. Luffy straw hat. :p
