What's cool about SJ is... two really good cocktail bars, a craft-brew-and-sausages place, and one really fucking phenomenal coffee shop downtown? The almost complete lack of violent crime relative to any other big city? The airport being easy to get to and low-traffic? The fact that it's an hour closer to Santa Cruz and Monterey than the cool parts of the bay? Oh, and the annual Taco Festival of Innovation is super rad.
What's not cool about SJ includes, but is not limited to: most of the people, most of the nightspots, a pretty good amount of the food, the odious rent (that gets worse each year), the sanity-grinding commute (that also gets worse each year), the techbros, the college students crowding up the couple of places that are decent, the ludicrously higher-than-normal rate of property crime against cars, the racist cops, the societal cruelty on display against the massive homeless population, the sexually harasser weirdos on the street, the amount of places that reek of piss (though it's no patch on SF here), and working in the vast suburban desert of south San Jose with no decent food or culture anywhere to be found.
I dunno, in 2017 I don't think I could in good conscience recommend anyone move here.
EDIT: I did forget the most important thing. GO SHARKS! ������
EDIT 2: All the pizza here is extremely bad except for one "New York Style" place that is actually New York Style and one Neapolitan place (which isn't much like any other kind of pizza you're used to.)
