The main reason to visit this mall is its 2790-sq-metre Secret Garden, one of the largest roof gardens in the world, with more than 500 varieties of plants (weekends and public holidays only). There's also a mini-rainforest in the mall's atrium and the climbing centre Camp5.
Otherwise you can expect themed mall zones, more than 700 retail outlets and plenty of places to eat.
The closest station is Bandar Utama (MRT), or you can jump on the LRT to Kelana Jaya and get a taxi the rest of the way.
