It was nice to sit there and eat, in the shadow under a tree... and many locals do that aswell! You had a nice view to the city, and there were some activities arranged in the park aswell. but you should be prepared, that as a tourist in central park, you'll get a LOT of attention, and many people staring... didn't bother us too much though; not as much as the ants in the grass, which we didn't notice until after sitting there for 20 minutes... and, watch out - to get there, you'll have to cross the highway. It's usually not a problem, since there is traffic stockings all the time, but make sure to walk together with some locals, otherwise you'll get smashed... driving in africa is interesting!
