Places of interest include the KL tower with a revolving restaurant, the twin Petronas towers, the palace, the war memorial etc plus the new modern city of Putrajaya just half an hours drive by car.This is a must visit place too. There are a variety of foods available for everyone. Fast food outlets like KFC, MAC,etc.to Chinese,Thai,Malaysian...endless choices.Add to that many street food joints near major tourist places.
We were amazed to visit the Times Square mall.It is really huge- ten floors of shopping and intertainment,and two towers upto 44 floors of hotel rooms with great views. The top of the mall between the two hotel towers has a big swimming pool.
If you love shopping you can spend days just window shopping in many such malls.But for fun and games you can become a kid too in the various theme parks in KL.
