This the the Catholic church in San Francisco. St Peter and Paul's church. It is downtown in little Italy, right next to Washington Park.
The last time I was there, I went in and went up toward the front of the church and lit a candle and was thinking about the family that have died since I was last there.
(very reverently) There were some very old people who were coming in and sitting down, I didn't think to much about it and then I heard some talking and realized mass was starting. whoops! I sat down in the second row and spent the next hour attending mass. (no, I am not catholic) It sure turned into a highlight of the trip for me.
Cheers to Happy !
