Built between 1988 and 1990, the Tokyo Metropolitan Government Office is one of the tallest buildings in the “Sky Scraper District” of Shinjuku. It serves as the headquarters of the Metropolitan Government of Tokyo (probably obvious from the name) and governs the 23 special wards and other sections of Tokyo.
One of the best views of the entire city, the Tokyo Metropolitan Government Office (MGO) is worth the trip to see and visit. And best of all it is free. The observation deck is located on the 45th floor on each of the towers.
There are other views of the city (from Roppongi hills, Tokyo Tower, Tokyo Sky Tree) but you are going to have to pay a decent sum to actually get up there and see those. Best is to get here around sunset if you can to see the city changing colors and the lights coming on. It is a government office so it is only open weekdays during business hours.
Cost: Free (Best deal in town!)

The tower is not that close to where the metro will drop you off. However the building can be reached completely by walking underground. Just do your best to follow the signs and try to keep your bearings straight.
