Denver has a longstanding love affair with sushi, thanks in large part to Sushi Den, the pristine house of Japanese seafood that brothers Yasu and Toshi Kizaki opened in 1984. As testament to Sushi Den’s status, chefs at just about every other revered sushi restaurant in town have spent time working here. Rather than resting on reputation, though, Sushi Den stays at the top with its commitment to the freshest seafood available.
