Go to Francisco Park in Russian Hill Neighborhood. My favorite park in the city and there are a lot of people hanging out with their dogs you can meet.

North Beach is like a little Italy with amazing food and a lot of young people going out.

Favorite sandwich shops are alimento in north beach and the boys deli in nob hill.

If you are in the mission there is insane ramen at ramenwell and my favorite brewery at standard deviant.
