Take the Blue & Gold cruise at sunset! Eat crab and get a bucket of donuts and check out the sea lions and you can even eat some In N Out! See Aquatic Park and enjoy amazing San Francisco scenery in a laid back ambiance.
You can walk across the Golden Gate Bridge! Just wear a jacket and layers :) And enjoy a coffee at the Round House Cafe.
Okay this might sound weird, but this is a really magical grocery store. If you have time, stop by!
