Mashiko Sushi and Katsu Burger are owned by same person: Hajime Sato. Mashiko is in West Seattle; Katsu Burger is in Georgetown. Mashiko is fancy; Katsu Burger is not. Mashiko is rational; Katsu Burger is nuts. It is good to go to Mashiko most of the time, but it is also good to go to Katsu Burger now and then. The former is about the body, the latter is only about the soul, which sometimes needs to gorge on something as crazy, as nonsensical as the massive, towering Mt. Fuji, a burger with all the major farm animals in it. (Katsu Burger, 6538 Fourth Ave S, 762-0752, 10:30 am–8 pm)
