The Opera House, that has changed for better and worse. In the 1970's and 1980's you would not want to walk on the west side of it, full of drug addicts and thieves. South side of it was a high school and sports field; a concert hall was built on the sports field site, and a state building was built on the north side of the Opera House - both improved the area in the early 1980's. Then the Loma Prieta quake in 1989 changed the west side - a damaged raised freeway was torn down at the west, City Hall got remodeled, and the area got gentrified with yuppie shops in the 1990s, forcing out the scummy denizens. Became a nice area in the 1990's. Then came the homeless to the east of City Hall in the 2000's, and they soon dirtied the area (Newsom's fault). One positive thing I can say about democrat Willie Brown, he took pride in cleaning up the area; can only say bad things about Gavin Newsom as he ruined everything he touched.
I’ve been to several major cities but none oozed such nasty odors in the air as San Francisco.
As for Newsom he has no interests in it’s cities nor the people...He’s just like Pelosi....power and revenue flow across his own palms.
