Meteor Garden is in Mandarin, from Taiwan.
I reccomend Densha Otoko of course (TV version was pretty good, actually. I haven't seen the movie yet, though)
What's that Korean Drama about the Imperial Kitchens? Dae Jeum Guam? That one's pretty good (and it has the same actress as Guem Ja-shi!! 可愛い！)

Also, I must reccomend My Sassy Girl (blanking on the Korean title right now, sorry). Best Korean Drama Ever. Period.
