The only thing I know about Malaysia is what a friend told me. She studied abroad in Malaysia while working on a biology degree. Anyway, she said that the tailors there are unbelievable. You show them a picture of an outfit from a magazine and they'll take your measurements and make it just as good as like Calvin Kline or whatever, but for pennies on the dollar. She said you could go there with $1,000 and get an entire wardrobe custom made for you.
Aside from that, it's also where she tried Mushrooms. Apparently they're rather common over there.
