NOTE THIS IS MY LEGO CITY AS OF SIX YEARS AGO, IF YOU WANT TO COMMENT/RATE MY CITY, PLEASE DO SO ON THE 2011 ONE, IT IS MUCH BETTER.
Here is my Lego City as of 2006, featuring a working skyscraper. Each level of the sky scraper can be used individually and is fully functional inside. When assembled on top of one another, they also have an elevator that moves between floors. The first level houses a Starbucks, clothing store, and video game arcade. The second level has a dental office with two dental chairs and a doctor's office with two exam rooms. There are also a reception desk, waiting room, rest rooms, and toy box. The third level is a food court with 7 different restaurants (Chinese, Mexican, Hot Dog on a stick, Pizza, etc.). The fourth level is a movie theatre with stadium seating (level 4 is a double height level), a projector room, ticket booth area, and concessions stand. The fifth floor is a casino, the sixth and seventh floors are condominiums (5 per floor), and the top floor is office space with large offices, conference rooms, reception areas, and rest rooms. This photo does not show all nine levels, but I will upload a photo soon to show the current status. I have also added windows to all levels and I am working on motorizing the elevator.
