I've just returned to Los Angeles after living abroad for almost twenty years. One thing that struck me was the virtual disappearance of ice cream parlors (that and book stores). Tel Aviv, where I was living, is exploding with artisanal gelato places. Here there they are few and far between When I was a kid, high end ice cream was the thing, starting with Haagen Daz, then Double Rainbow, etc. Now it's been replaced by frozen yogurt and shaved ice. Only the dinosaurs, like Baskin Robins, long eclipsed by the high end places, are still thriving.
