While staying at the Sheraton (reviewed separately) I decided to take a stroll in the Sheraton Gardens right next door. The gardens are beautiful, clean and well maintained, and they give a bit of a reprieve from the hustle-and-bustle of the city around you. It also has a big water fountain (empty when I visited) as well as some statues spread around including the Independence Monument. If you are in the area it is definitely worth spending some time there, even if just for a quick 10 minute stroll.
