Take some of Asia’s biggest malls, hundreds of
street-side vendors and a dozen of posh hotels and
you’ll have Siam - Bangkok’s commercial district that
will make any shopper’s heart beat faster. From cheap
electronics and wholesale goods in MBK to designer
handbags in Siam Paragon, you’re almost guaranteed to
find what you’re looking for in one of Siam’s many
malls. Take a break from the commercial craze and

I had to wait for about 20mins because the restaurant was full, I was able to reserve when I got there & then came back later. Not sure if you can reserve by phone though.
