Macau

I did not really know what to expect from Macau, what i found was a mix of:

Vegas - bright lights, a bit tacky in places;
Portugal - you certainly get a feel for the portugese influence in the architecture, town planning etc..
China - of course the dominating feel is the hustle/bustle of china, high rise housing everywhere but combined with culture, religion.

You can walk around and see most of the sights on foot, including the old town, city ruins, fort and museum (which was really good). Overall a decent location for a few days trips.
