This is one of those, "Why didn't someone think of this sooner?" concepts, and it makes sense that the tempura-fried hamburger was created in sushi-crazed Seattle by one of the city's celebrated Japanese chefs. Katsu Burger – so named because the popular, panko-coated pork cutlet dish tonkatsu was the inspiration – is tucked into the corner of a strip mall. Unassuming inside, as well, a handful of tables make up the tidy, minimalist dining room. The squeeze is worth it to sample Hajime Sato's 12-burger menu, each available in beef, pork, chicken or tofu. Basic versions are topped with shredded cabbage, tomato, red onion and pickle – or create your own concoction. Can't decide? Go for the belly busting Mt. Fuji, assembled with one each of the meat patties, cheese, bacon, wasabi mayo, spicy mayo and tonkatsu sauce.
