Japanese folks visiting L.A. know to head to Kasen for high-end omakase sushi. It’s very old school–sometimes they try to persuade non-Japanese people to go elsewhere, thinking they want California rolls, teriyaki and the like. Stick with it and profess your love for traditional sushi, and you’ll get excellent, super-fresh sushi; russkar prefers it to Costa Mesa’s well-regarded Shibucho.
Omakase is pricey, but at lunch it’s a reasonable $35-60.
