You must see the Bay Bridge!! There is a beautiful light show that has been installed and there are plenty of wonderful seafood restaurants along the Embarcadero to watch this from including my favorite, Waterbar. This is the part of the city that has a much more urban vibe since it is close to the Financial District. You can see the sparkle of downtown. It is a little bit away from the parks so you can see that concrete jungle essence in full throttle.
