The most famous building in Malaysia is the architectural wonder of the Petronas Twin Towers in Kuala Lumpur, the largest twin towers in the world and with the highest sky bridge in the world. There is a huge shopping mall at its base. You can buy a ticket and enter the sky bridge but tickets are limited and sold out very early. A better alternative is the TV tower, which is actually higher, if you want to get a view of KL from high above.
Malaysia still has pristine rain forest and several National Parks are worth visiting. The large Taman Negara in the center of Peninsular Malaysia is for most people easiest to visit, but if you have the time be sure to visit the Borneo part.

Being a crossroad of Malay, Chinese and Indian cuisine, with a certain British and Portuguese influence, Malaysia has probably one of the most diverse choice of dishes you can find anywhere in the world.
