Living in the Bay Area, I find the food scene amazing. I do, however, find the food scene in San Francisco bland and repetitive.
The same pattern holds for cultural activities and the outdoors; SF has the same things over and over again, while the Bay Area as a whole has an abundance of options to fill your life with. I have also found that many people who move to San Francisco spend 99%+ of their time in SF.
I do agree with your sentiments about what a large amount of people in the Bay Area want to spend their time thinking and talking about. I stopped going to parties years ago after I couldn’t find a conversation that wasn’t about how this dude worked at Apple.
