High quality fish with an awesome sushi chef who created a fun and inviting environment. The sashimi and fish were all of very high quality. I also enjoyed the seasonal menu of interesting appetizers including the chili shrimp. Getting to talk with the chef and owner really added to the experience.

Overall: A+ only one trip up...the poke bowl First pic is the poke. It was just a mess in flavor. Big miss. BUT the rest was amazing. Sashimi plate, toro tuna sashimi, chopped toro and rainbow roll. Everything was very fresh and clean flavor. Will definitely be going back.

If you want to enjoy an authentic Japanese sushi experience while in the luxury of California, go here!! Definitely opt for the bar seat for the best experience of Japan. I thought I was in Japan again until I stepped outside and felt the SoCal sea breeze. Fresh fish, excellent sushi chefs, and true Japanese hospitality.

A perfectly comfortable yet classy place to have the most fresh sushi. Service is quick and impeccable. The sushi chefs, if you sit at the sushi bar, will recommend the freshest catches. The live scallop was a pure delight! The bluefin Toro was like butter.

Seating for 2 at the bar in front of the chef. We went right before the Pandmeic started. It was a special night. Told the waiter we wanted to spend around $100 per person (not including drinks) and surprise us. We were served 10 small unique phenomenal dishes. Such a wonderful experience!

Koi, you never disappoint. Went here for a bday dinner Omakase. And since recently, we have had amazing Omakase in Japan, the bar was set pretty high, and boy, let me tell ya, it did not disappoint. We sat by the bar and asked for Omakase with Shin-san. And I trust him with all my heart and tummy. Loool! All the fresh fishes, local and important was just so fresh and greatly prepared. The Black cod appetizer truly melted in your mouth good. Shin-san also made the birthday dinner by preparing a special dessert! Shin-san really made this 3xperience so worthwhile, the service is even better than we evrr had in Japan. Definitely a splurge for Omakase but so worth it. So glad that a lot of the locals frequented there and the chefs knew rhem by name. Now, that's dedicqtion and love in their craft. The waitresses are always so courteous and attentive. Koi, you didnt disappount me then and you didnt disappoint me now. My ever favorite place for Omakase in SoCal! ありがとうほざいます。ごちそさまでした。

The only thing difficult here was to decide what to order. Albacore is my go-to for an appetizer, and it was delicious. I ordered the sashimi dinner and loved everything except the red Tuna. Portion size of the salad was very generous. Not pictured is the Miso soup, standard and tasty. Great dining experience, food was wonderful, and we will definitely return.
