Take a seat at the counter of this nondescript storefront in a strip mall wedged between Beverly Hills and Culver City, and Keizo Seki will dazzle you with 24 different cuts of fish, including a number of varieties that you probably have never seen before. Seki is a purist, and if you dare to ask him for a specialty roll or some other type of concoction served at more Americanized sushi restaurants, he will respond by barking, "We don't serve junk here." Our reviewers clearly seem to agree with Seki's boast, telling us that "This tiny omakase-only restaurant serves some of the best and freshest fish I ever tasted." But there are downsides. Besides the lackluster ambience (one reviewer compared it to eating in a Subway), the beer list is limited, and there's a no-BYO policy.
