There's a decent selection of food in the basement as well as some fast food at the 4th floor. Furthermore it offers a quite large selection of stores (from high- to low-end). It's worth a visit.
This is the perfect spot if you're looking for stylishcomfyclothes and stylishshoes. Very comfortable and durable. A bit pricy though, but it is worth it.
The fountain show starts every hour and last for 15 minutes. It can be watched from the B1F up to the 3rd floor! Don't miss the top deck view either on the 13th floor!
Omurice at Rice Express is to die for. Note: Waiters know very little English so polish your Korean! The Fountain Light show at the Atrium is a must see!
