Bukit Bintang is the central area in KL. There are many shopping malls and restaurants. It's easy to come here by the monorail. Also, if you would like to exchange some money, I would love to recommend you to exchange in this area. You can walk around to compare the rate of exchanging money. It is really good to walk and chill out in the evening till night time. You will enjoy dining and drinking in cheap to fancy restaurants and bars.
