5 star all around! It's rare to find Japanese restaurants that are Japanese owned and operated now. This is a gem!! Came for lunch and got the sushi omakase for $25, with added tempura, salad and udon or soba for $8. Crazy good deal for the quality and variety. So delicious!! The sushi melts in your mouth. They have tempura matcha salt and homemade wasabi. These are usually only at high end places. Even gave us a sweet birthday dessert. Our server was super sweet and kind. Can't wait to come back!! read more

We came to K's Bistro on a Saturday night to celebrate my sister's birthday and got the special omakase. We made reservations in advance and were seated at the bar in front of the chef. The appetizer and the uni toro ikura bowl were definitely the highlights of the meal. The hokkaido uni was SOO fresh and sweet. The edible flowers made a nice touch to the uni toro ikura bowl. The quality of the fish was amazing, I would definitely come back to K's Bistro if I'm ever craving for omakase. It was truly an impeccable experience. read more

I visited for lunch and found the establishment to be a charming, intimate setting. The service was exceptionally professional, courteous, and polite. The two sushi chefs were also very friendly. The restaurant's traditional Japanese aesthetic, reminiscent of Japan, was quite appealing. For lunch, I ordered the omakase, which was priced at one hundred dollars. I also added an extra appetizer, which, in retrospect, was unnecessary given the generous portions included in the omakase set. The sushi was excellent, very flavorful, and beautifully presented. I thoroughly enjoyed every dish. I highly recommend this establishment, but I strongly advise making a reservation due to its limited seating capacity. read more

Exceptional delivery on quality and experience. Interiors is modern with moody lighting- perfect for a date night or elevated dinner out. Servers were super friendly and attentive. Some of the freshest fish ive had at any sushi spot in OC or LA. They also carry selections from Japan that you rarely see elsewhere which makes the menu more unique. Its hairy crab season so it was great to see they offered that as well. Prices are definitely on the higher side but you can taste the quality in every bite. You get what you pay for. read more

Parking is in a shared lot so had no issue finding any. Inside is a small intimate space very nice ambiance. We had no reservations & were sat right away. Our server was fast & friendly. We sat at the bar which was fun to watch them make the sushi. We got the miso soup which was good, the blue fin tuna, salmon, & some other fish I forgot the name of which was delicious. Prices were a bit high but great quality fish. read more

Stumbled upon this place about a year or two ago and it has not disappointed since. The omakase menu includes a nice mix of cooked items and nigiri. Both the staffs and the chefs are personable. Parking is limited in the plaza, but can always turn to The Camp as an alternative. read more

i didnt know what to expect when i arrived to the restaurant esp with its unassuming storefront. its easy to miss bc there arent windows or anything. but im glad it is because it felt like a hideaway! the sushi bar is very brightly lit but we sat at the tables. it was a little more dim over there. service was really good. they are very attentive and time the meal perfectly for omakase. the food was delicious! i loved every piece of sushi and the wasabi in each piece wasnt too overpowering or heavy. high quality fish and amazing flavor combinations from the chef! definitely a memorable omakase experience to celebrate special occasions! read more

Love this place. The food is so fresh and good. The nasumiso is phenomenal for anyone who likes mushrooms and eggplant. The carpaccios are all in a deliciously flavored sauce. Small and quaint place.

Had the bluefin carpaccio, blue crab cut roll, rainbow snapper, red snapper, Takowasa, amberjack belly, salmon collar, fresh scallop and baby fried river crabs tht were out of this world. coming back again real soon.

If you're looking for premium omakase or high-end nigiri in OC, K's Bistro in Costa Mesa is the real deal. As someone who's been to dozens of sushi spots across OC, LA, and the Bay Area, this is easily one of my all-time favorites. The vibe genuinely feels like a small, authentic sushi chef's restaurant in Japan -- intimate, cozy, and focused on craftsmanship rather than flash. It's not ideal for large groups, but that's part of what makes the experience feel so special. I tried a variety of incredible cuts, including golden eye snapper, halibut, red snapper, Spanish mackerel, and amberjack -- all beautifully presented and truly melt-in-your-mouth. The A5 Wagyu was unbelievably tender, and the bluefin tuna carpaccio with real truffle shavings (not truffle oil) completely blew me away. You can taste the difference immediately. The service is just as impressive as the food -- from the servers to the sushi chefs. Everyone is attentive, welcoming, and makes the experience feel personal and elevated. Whenever I'm in OC and feel like treating myself to high-end nigiri and omakase, K's Bistro is always at the top of my list. If you're a sushi lover or want to impress someone with a truly refined Japanese dining experience, this place is a must. read more

Came here to celebrate both my friend's birthday and mine, and it turned out to be an amazing experience. I ordered the $120 omakase, and it was well worth the price. Every dish was delicious, with perfect timing and portion sizes. These days, it's hard to find places (Especially Japanese restaurants) that truly deliver for the price, but this one absolutely does. Both the chef and our server are Japanese, and the experience genuinely felt like dining at a restaurant in Japan. A rare find and a real standout. We mentioned it was our birthdays, and they surprised us with a thoughtfully decorated birthday dessert, which was such a nice touch. Highly recommend. read more

Amusing Diners, Drive Ins, and Dives says "If its funky, we'll find it." Uh, okay. So find me a run of the mill strip mall in Costa Mesa next to a kinda upscale dive bar cocktail bar and you'll find the best sushi-focused Japanese food anywhere in the United States...........? We found K's by accident and believe it's meant to be. Truly exceptional, not just good, everything. Master class in sushi preparation, exceptional service, and I would put K's up against any Michelin star Japanese restaurant anytime. Simply said, if you're within an hour and never ate here, you should probably make the trip. read more

A happy Yelp find, Sushi K's Bistro was a wonderful discovery. Be sure to RSVP for this popular spot, as the intimate space fills up quickly, and the shared parking lot can be limited. The outstandingly fresh ingredients shone through in every dish, from the first bite to the final snow crab hand roll. We loved the Hokkaido uni, toro, and the ikura served in a shot glass. A standout was the Monk fish liver--incredibly fresh, lightly warmed to a buttery perfection with no fishiness. The drink selection was ideal, with a perfect beer list and unique options like the yuzu sake. Sitting at the bar to watch the chefs in action made the experience even more enjoyable. We will definitely be back. read more

Hidden Gem Alert This spot is very small .5 tables & the sushi bar so make reservations! Service is impeccable! Interior is very understated & clean. This is a great date night idea. The basic Omakase is $100.00 the premium with Japanese Fish is $150.00. It's actually a lot of food & the best value imo. I got the basic & our friends got staters & rolls. The small bowl that comes with Omakase was Ikura & Uni with a small dollop of caviar & it was so heavenly ! My favorite pieces of the 8 sushi was the Japanese scallop . The rice was cooked to perfection, all the fish was cold& the presentation was top tier. I'll definitely be back here ! read more

I Had Suchhh a Wonderful experience at K's. It was so nice to be around the chef and observe them make some splendid servings w a delicate touch : the most truest experience you can get in America w the essence of the Japanese cultural exp. The restaurant itself for some intangible reason gave cozy but in polarity a spaciousness that overall added to the exp of intimacy and community. I love this place, The Cuts straight from Japan are a MUST TRY. So soft and fresh, no aftertaste that left me feeling discomfort. And the Servers!!! Shoutout to their knowledge and connection to the chefs, I loved hearing their interactions as I enjoyed my special solo meal - I didn't feel alone in this exp whatsoever I shall be back on special occasions to this restaurant - a wonderful spot for a treat or a date in my opinion ~ it jus has that nice vibe read more

K's Bistro is my wife's and my go-to omakase spot. Small, intimate, and unassuming, like having your own little hidden sushi den.

KS Bistro is a hidden gem that completely exceeded my expectations. The staff was attentive, which made the whole dining experience even better. The food was absolutely delicious. You can tell a lot of care goes into each dish. We ordered some nigiri, the dragon roll, sake sampler and added the shishito peppers and wow. Everything was flavorful, fresh, and beautifully presented. The sampler had great variety and made it easy to try a bit of everything. If you haven't been to KS Bistro yet, definitely give it a try. It's one of those spots you'll find yourself coming back to again and again. read more

Talk about a hidden gem. It's so hidden, you can't really see it from the street and don't let the 152 reviews dissuade you from trying it. This place is so good. Believe me, I had my reservations when I saw that there's only 152 reviews and when I drove into the parking lot and saw it from the outside, I had serious doubts. But boy, was I wrong. The parking can get tricky at night because of the bar that's next door. As you walk in, it's very small. There's only 4 small tables (for parties of 2 or 4) and a sushi bar that seats about 8 people. We were lucky to get a table on a late Thursday evening and while it wasn't packed, it was pretty full with a good rotation of customers coming in and out. I'd recommend reservations, especially on a weekend. They have so many different types of unusual fish in addition to their traditional staples. The freshness and quality of their fish is just amazing. If you don't want to do a full omakase and rather leave room for other things to try, definitely go with their 5 or 8 piece Chef's Choice. And, you can let them know if you have any preferences and they'll cater to it...amazing! Their non-sashimi items (i.e. Kushi aka skewers, beef tongue, home made tofu, pickles) were also really good too. We also got a Rainbow roll which was good...don't get met wrong but there's not much you can do with a sushi roll that would make it super amazing. They have a "Today's Special and Recommendation" menu that has new/variation of things and highlights that change from day to day. So I'd definitely save the $ and room for other non-roll items next time I visit. read more

Had a fantastic time here for a pre Mother's Day celebration! This small hidden gem used to be IKKO (in the old days) and I was curious to see how the K's would in comparison to my beloved IKKO. This restaurant is small, with 3 tables and probably 10 seats at the sushi bar so make sure you make a reservation. The service was friendly, attentive & accommodating, as we had many questions compare to other patrons. The ambiance of the restaurant shifted swiftly from somewhat quiet omakase sushi bar to a lively izakaya as the night gets late. Now the food- some of the highlights were abalone in liver sauce- the abalone was so soft with rich liver sauce. It comes with sushi rice afterwards and may I say the sushi rice it self was so good already and with the rich liver sauce it was beyond amazing! Ikura - done RIGHT here! Bursts of umami in the mouth as you bite through it. You can definitely taste the seasonings- I am guessing some bonito stock, soy sauce & sake. The flavors really shines through! Chefs choice of sashimi (8 kinds)- I could go for a second round of this! every piece of fish/shellfish was fresh and a great start to dinner! Hairy crab- this is a super labor intensive dish as every little nuggets of crab meat are stuffed inside crab shell. So for y'all lazy crab eaters out there this is your crab paradise. Crab was fresh, delicate & the dipping sauce really gives it a different dimension. It's nice to have a decent sushi bar that opens late and opens for lunch so we don't have to rush to lunch or dinner on a busy day! read more

The sushi lunch combo was absolutely delicious and a great value. Fish tasted very fresh, with good texture and no hint of fishiness. I also appreciated the light hand with the soy sauce and fresh wasabi to let the sushi shine. Notably, the rice was a nice al dente texture such that I could taste every grain. And the presentation was immaculate. Felt like high end quality for an approachable lunch price. The lunch sushi combo came with: - Medium fatty tuna - Yellowtail - Fuji trout (similar to salmon) - Spanish mackerel - Barracuda - Red snapper Also: 2 pieces of tamagoyaki, 4 pieces of california roll, and miso soup. The red snapper was my favorite, with the clean flavor highlighted by the seasonal yuzu zest. It reminded me of the Taimeshi in Matsuyama, still one of my favorite meals in Japan. read more
