You went to a few sushi roll places and now you want to demean the quality compared to Tokyo? Give me a break. I’ve spent months in both and you’re not painting a very fair picture. Tokyo is the sushi capital of the world. No one would dispute that the Japanese have the widest variety of amazing sushi. But San Francisco is way up there and if anything the problem is there are too many unaffordable omakase menus with the best fish from Tsukiji market in Tokyo or from Monterey Bay. There are places that sell California rolls to tourists like everywhere, but San Francisco has so much actual Japanese food and so much omakase that I find it absurd that you characterize it that way. There is no way Chicago can go toe to toe on Japanese restaurants and you know it.
As for drinking sake cold, if you spent much time in Japan you’d know they typically serve crappy sake warm to disguise the impurities of not having polished the rice enough before making it. A good Junmai Ginjo will be served cold. You are welcome to have sake however you want, but don’t blame San Francisco for knowing how to drink sake properly. In fact, San Francisco has the only sake store in America (True Sake) because there are so many Japanese people and it’s so popular.
