A big shopping mall
That country is a big shopping mall, if you like to shop, you will be in heaven. If you like architecture, you will be in heaven as well. Otherwise, you get bored pretty fast. You can go around the whole country in 2-3 days. Quite artificial westernized place if you ask me. People are not that nice since they are in a hurry to go working or shopping. Locals actually hang out in malls and go from one to the next all day. I guess it depends on what you like to do or see :)
Insider Tip:Take a hop on / hop off pass that you can use with the Subway as well. If you smoke, buy smokes before getting there as it is quite expensive.
