Siam Discovery

The newly renovated Siam Discovery, located next to Siam Paragon, has an eclectic mix of Asian designer shops and speciality stores, international brands such as Diesel, Apple as well as a Madame Tussaud's museum on the 6th floor.

If you are looking for something more specific on the fashion front, then this place might be worth a look. There is a useful, air-conditioned walkway between MBK and Siam Center.
