Walk on the North (water) side of Embarcadero and you can walk unimpeded by traffic lights. You can still catch a few glimpses of Fisherman's Wharf in between the tourist traps. Beautiful views of the Bay, Angel Island, Alcatraz, and Telegraph Hill
There are many shops here. Go see the sea lions at one of the piers, can't think of the exact one off hand, and fight the crowds. Or at least fight them in June. The weather will be a lot cooler than you would think so if you are cold-natured, bring a light jacket.

I'm a native so I pretty much don't visit the tourist spots unless I'm showing company the city. Yet, it's an SF must see. There's been a trend of casualizing the area. The Franciscan used to be a place to dress up to...as was ASabella's which is now an Applebees. Nothing wrong with that, but the area is changing.
