western addition

A huge and diverse hood in San Francisco that is bordered by Haight, Pacific Heights, the 'Loin, and market. Fillmore is often considered part of the hood, but is distinct in its own right. The area is full of life with plenty of bars, restaurants, clubs, markets, specialty shops, and cannibis clubs. Everything is so compact that driving is unneccessary and droves of party prone people walk the streets at all hours of the night, a hipper neighborhood in San Francisco.

"i wanna move" "look on CL for a place in Western Addition or Mission, thats the place to be!"

Student 2: "Yeah, must've been a case of 'addition by retraction'."
