If menus are flavor road maps, the one at Hannyatou—Mutsuko Soma’s Fremont sake bar encore to Kamonegi—first takes you to Japan with fluffy sandwiches of omelet cooked with dashi. Then into pleasantly offbeat territory. Soma’s “I can ferment that” attitude yields a malted onigiri rice ball with salmon bits that’s topped with a gently torched layer of miso made from jalapeño cheddar bagel. It’s a salty-great destination in one bite.
