Were you a fan of Full House? I remember watching it as a kid and in all the times I've been in San Francisco, this was the first instance I've been in front of these Victorian and Edwardian homes! It was extremely crowded but everyone is very civilized and there's enough room to take pictures without anyone else photobombing your shot! I stopped by the Alamo Square Cafe right before coming here to grab a sandwich and it was delicious (you'll find it if you walk along the perimeter of the block with The Painted Ladies)! Whoever created Dutch Crunch Bread, I love you (see picture below)! You can find this landmark location between Steiner Street and Hayes Street in SF. 

The other snaps below were taken near and at Japantown. My mom and I walked there by foot and it's fairly easy and flat... unlike the rest of SF! Have you been to these places? Would you want to visit?
