Kappo Sui

Excellent sushi, reasonably priced and very good service. Location is nothing special in a strip mall, but if you're looking for good sushi, Kappo Sui is a good choice

This is the most Japanese authentic Kappo restaurant in OC. If you like j Japanese food, it is worth to try !!

Nice little authentic Japanese restaurant. Interior is a bit dated, but the food is good.

Kid-friendliness: I never write reviews, but due to exceptional quality Japanese food wanted to share our experience. Excellent food with wonderful staff. The Bass is as good as Le Bernadine in NYC. All very fresh delicious food. Kid friendly. Wonderful surprise looking for Japanese food. Will definitely be back! Must try!!

You HAVE to eat here!! … I’ll make this review short, but I was beyond impressed and so delighted to have found this hidden gem. Not only is the food incredible, but the fish is some of the freshest and most flavorful I’ve ever tasted. The wait staff is also simply fantastic My business partner and I asked chef if we could order omakase , he joyfully obliged - and it was the BEST sushi assortment I’ve ever had. I’ve paid over $200 per person for omakase on special occasion in San Francisco, crafted by a world renowned sushi chef … etc. This small humble family owned restaurant in Costa Mesa, gave me such a sense of satisfaction and connection to the food that I have not felt in a long time. And for that, I thank you ALL at Kappo Sui! See you soon

I don’t even know where to begin. I was in town on business and met with an associate. We had no idea where we were going to go. Just started in Costa Mesa and took off driving. Finally, I randomly picked this place off Yelp. We pulled in and admittedly I was reticent. It’s very nondescript. At the end of a strip mall, I thought it would probably be one of those places that really good or really bad. The best way I can describe the color scheme inside is 1990s Taco Bell light blue and pink. We walked in, and the place is about half full. Immediately we noticed that every customer (at that time) was Japanese. Taking that as a good sign, we stayed. Suffice it to say, this establishment was a revelation. My associate is a foodie who has traveled the world and has sushi at least a couple of times a week. He lives in SoCal and he’s had hundreds of styles from restaurants in the area. We were there for 2 1/2 hours. I think we ordered five courses. I’m not as educated in the cuisine as he, but everything we put in our mouth was absolutely exquisite. He stated that it was some of the best food he had ever had in any of his travels. I am 53 and encountered some flavors I had never experienced. The two of us spent hundreds of dollars, mostly because we (and my associate especially) couldn’t believe the quality, freshness, and deliciousness. We could not stop trying things! Zuke, our server, was amazing too. I think he was amused by us and it might’ve crossed his mind an hour in that he should probably get a form of payment considering the amount we were ordering :-) Do yourself a favor and visit this place. My associate is already making plans to drive an hour and a half with his wife to visit again, get a hotel room and make a night of it. I will never go to the Irvine area again without visiting Kappo Sui. I can’t wait to take more friends and associates, and hopefully this review allows you to make the same great decision.

I had an amazing experience at Kappo Sui! It was the first time they did omakase and they hit it out of the park! The fish was super fresh and the rice was perfect, definitely coming back. Kappo Sui also has monkfish liver/ankimo, which is my favorite! The service was lovely and everyone was friendly. It wasn't too loud so my boyfriend and I could talk and hear each other.
