Tucked in a Japanese supermarket is probably one of SF:s "hidden treasures". Go for the infamous coffee crunch cake, if you get your hands on it when the store opens. (Apparently, you can pre-order, but not sure how that works.)
Personally, eat the cake at room temperature, not straight out from the store's tray.

The bakery is somewhat hidden within a Japanese grocery store. Still, given the fame that this bakery has achieved, there was already a line before the store opened.
They are pretty efficient at taking and fulfilling orders so the line moves at a pretty good pace.
Their most famous creation is the coffee crunch cake. While the cake itself is pretty ideal in terms of texture and taste, I found the actual coffee crunch outer coating to be all too-sweet, which was surprising to me. I figured a Japanese sweet shop would not hew so closely to the overly-saccharine taste of western shops. Still, a fine tasting cake.

The best place to get a cake for any and all events. I've noticed I actually have been looking for occasions to buy a cake from here because they're so damn good. You can call in to order in advance.

Best coffee crunch cake in The City. We get this tall cake for birthdays. My aunties tell me every time we eat this cake - "The recipe comes from Blum's" (an old-time beloved SF bakery that went out business decades ago (as in the 1970s)).
Not too sweet. Light and airy sponge cake with whipped cream frosting. This is what heaven tastes like. Lots of coffee crunch all over the frosting, but you can pay extra (which my family does) to add more coffee crunch topping to your cake if you special order. Ordering a whole cake is a little pricey, but it's definitely worth every penny. Yasukochi's cakes are never wasted with my family.
