I highly recommend it
The KL Menara tower is situated in the city center and offers an interesting 360 degree view of the whole town, and the Petronas Towers. It costs about 30rg and when you pay the entrance fee, you will go up in the elevator accompanied by one of the nice members of staff (all were very helpful and nice to me) and give you a kind of iphone with headphones. They ask you what language you speak and a very nice gentleman who speaks Spanish with a rather strange accent appears, telling you what to do when you're in the area which are the buildings you should see and a little history about each. It is perfect to inform you about some of the places to go, because in a country with such a mix of cultures and races like that in the beginning you feel kind of overwhelmed, but you have to take your time.
