lol I'm from KK even though I've never really lived there. Do your research first before coming. The islands just off the city are gorgeous or go inland to Kundasang. I don't think there's much to do in the city itself.
My husband did night diving and he loved it. I have to say in Malaysia generally you need to research the restaurants you're going to, in Thailand almost every stall and restaurant is good but not in Malaysia.
