We hadn't been to Yamaguchi Restaurant on Main Street in a while, and I'm so glad we went back! Under the new management, the place has a completely new feel, the new decor is great and super welcoming. The food was incredible, everything was so delicious. But what we loved most was how friendly and attentive everyone was; they made us feel right at home the whole time. Plus, their lunch special is a really good deal, super reasonably priced and great portions. If you're looking for a relaxed spot for lunch or dinner, definitely check them out. We loved it! read more

Restaurant Yamaguchi - Japanese Near Me - Port Washington, New York

This is a solid Japanese experience with a diverse menu, and closest to an actual Japanese feel. I knew right away that this place was gonna be good when my Japanese au pair said the Toro was a 9/10. Also, the agedashi tofu was very good, and most places get it wrong. The chicken teriyaki was perfect and tender and I'm mostly certain they cooked it sous vide. The wagyu beef was apparently very tender and delicious according to my family. They could use more dessert options but we loved the cheesecake. Service was fine. We will be back for sure. read more

This is an updated review - we decided to give this place another try after a 2 year break since we had such a poor experience last time. It looks like it is under new ownership, new waitstaff and menus, etc. The previous rude waitress is no longer there, much to our relief. We did not experience any changes in food quality or portions under the new ownership. The prices were around the same as last time, and fish is still fresh and tasty. Service was excellent, our waiter was very attentive and food was served promptly. My husband got the omakase platter and I did a la carte, the toro sushi is excellent and highly recommended. Happy we can come back here once again. read more

Looks like the new owners and new menu, also renovated. They have some specials that give it a more modern twist. Hamachi Kama was delicious and well cooked. The yamaguchi roll and sashimi was just okay. They had kinki fish which is from Japan- it was certainly something I've not tried before- I preferred the hamachi over the kinki but it was prepared nicely. read more

This used to be owned by a lovely Japanese couple, the husband being the head chef, up until a week ago who served authentic and delicious homestyle Japanese food and the freshest sushi where fish was flown in from Japan as well. Well Sadly that has come to an end as of March 2025. They stayed afloat by offering take out only during the pandemic with a limited menu but finally came back into the full swing of their menu when they started opening again for dine in. Sadly the owners have retired and moved back to Japan and the new owners are not Japanese and have already removed most of the homestyle options on the menu that the locals and out of town visitors alike would come here to enjoy. The restaurant was full of screaming chinese speakers from the patrons and the staff and they had their contractor walking around with an employee darting in and out between tables looking at what's to fix and change. I didn't choose a Chinese restaurant to go to for my dinner. Food was not as it used to taste, the spicy roll was bland and the rice had too much water added to it that it was mushy and tasteless. It was good to see a couple of familiar servers that used to be there with the old owners but service with the new staff was not how it used to be either. Sad to see another authentic Japanese restaurant not be that anymore. read more

Came here on a Saturday for lunch. The sushi and sashimi were fresh, with a good variety to choose from. Highly recommend their combo set. We'll definitely be back! read more

The fish is very fresh and the omakase choices are wonderful. Unfortunately they are understaffed so your wait time will be high to get a table, to get your order taken, and to get your food. You'll be glad you ordered sushi. Lots of great choices in the omakase. Come by quickly. read more

April 30 Kumamoto oysters, fresh, delicate, still vibrant after their trip from Japan. Available most days at Restaurant Yamaguchi. April 23 Two special five-star items I tasted today at Restaurant Yamaguchi. (1) Bluefin tuna marrow - like a clear fresh jelly. It is only available some days. Never had anything like it before. (2) Botan ebi sushi - raw sweet shrimp (similar to raw scallops) with edible fried shrimp head. April 4 Live scallop available some days. I had it today. Very special. March 18 The lunchtime Grand Opening with new management did not disappoint. On the contrary, its Sushi A entrée was a near-perfect experience. Not only was each item (tuna, salmon, hamachi, etc.) on point as to mouthfeel, taste and temperature, what sent my evaluation over the top was the usually quiet corner in dishes like this, the scallop and the shrimp. While food writing is always a problem of translation, I would describe the scallop and shrimp experience as pleasingly "ocean-bright." Best of luck to the new management! read more

Restaurant Yamaguchi - Best sushi! - Japanese Near Me - Port Washington, New York

I an Omakase lover. I say this so you understand the intent of my review. I've eaten it every high-quality omakase restaurant in New York City. This restaurant houses secretly some of the best Nigiri you can get a Long Island hands-down. Go sit for Leo at his bar. read more

Great fish selection, mostly from Japan. On par with high end restaurants in Manhattan. I think is the best fish selection in Long Island. This restaurant for connoisseurs omakase but with great price & also with great selection from kitchen cook food. Friendly service. They have foie gras, wagyu, Shima aji, kinmedai, blue fin toro, rosy Seabass etc you name it.The only draw back is The music can be more upbeat. read more

I was concerned when new owners took over Yamaguchi on Main Street but my fears were allayed when I went there. It is currently my favorite Japanese restaurant in town. The fish is swimmingly fresh and they execute the standards like teriyaki and katsu dishes well. They are also open for lunch and 7 days a week. The lunch Bento box is a deal! read more

New ownership, didn't have a same experience and honestly doubt this place will last. Preferred going here for its authenticity, now it's like every other place. Sushi was smaller and took a while as they were still trying to understand service. The waiter had his finger in my salad bowl and had his pen touching my wife's salad. Has all the right signs of things not going well. read more

I hadn't been to Yamaguchi since the new owners took over, and now I really miss the original owners. It used to be a traditional Japanese restaurant that I truly enjoyed dining at, but now it feels like just another overpriced sushi spot. I'll stick with my favorite place in Queens instead--better quality and about 10-20% cheaper for my sushi fix. read more

Let me preface this by saying that Mr & Mrs Yamaguchi are family friends with my Japanese mother. I'm half-Japanese (& half-English heritage) but a born & bred New Yorker & Long Islander to the bone. I'm not a consummate restaurant worker but I have helped the family at the restaurant. So my view is biased but I aim for objectivity. Now let me alert you that Mr & Mrs Yamaguchi are retiring & have sold the restaurantIf you want to try the restaurant or love it you better try to get in there before January 31, 2025 before things change JANUARY 31, 2025 is the last day for Mr & Mrs Yamaguchi before retirement. Yamaguchi is one of the only & best Japanese restaurants serving authentic & traditional Japanese cuisine on Long Island. In a couple of weeks that will change. I cannot pronounce that it will be after January 31st as I am not a fortune teller. So if you've never tried it before I highly recommend give it a try. read more

it was my first time of trying this place. it was an excellent experience I had there. Food was fresh and delicious. Will definitely come back again. Recommend Sushi Sashimi Combo. read more

Do not go! New owner and the quality of the food is disappointing!! Now it is just another Chinese Japanese sushi restaurant.

You should like it!!" (see image!) We are NOT going back! read more

Love this husband and wife restaurant with high quality sashimi and variety of Japanese dishes at such a reasonable price! The sashimi Omakase is fresh and mouthwatering with hon wasabi. The tempura and tonkatsu batter is crispy and light without being too oily or having the reused oil taste. The uni is heavenly as if it was just cracked open from the shell. The appetizers with squid or octopus are tender, tasty, and worth coming back for. Service is friendly and generous. Parking is ample in the back of the restaurant. I'll be back for sure! read more

Restaurant Yamaguchi - Sashimi Omakase - Japanese Near Me - Port Washington, New York

i was in a local facebook port wash group and knew about new ownership before coming here. The fb group talked about how the owner will strive for the same freshness...etc... - sushi was good. - it definitely got alot smaller than before. I remember the yamaguchi used to be "wow its such big piece of fish" and now its average. - price, i think its about the same as before. not much difference. - I was the first table on Saturday , walked in at 5pm. server was okay, average, they dont bother me, i dont bother them. However , when my kid put the last piece of salmon in his mouth, and i was still drinking my beer on my hand - the waitress came by and asked if i my wife still needed anything, and my wife said no. she took away all of the plates, yes my son was still chewing with chopstick on his hand, and within 45 seconds when i was still holding my beer - she brought over the check and walked away. i was the still the ONLY table in the entire restaurant.. I thought she was very rude for doing that. My wife also thought so... needless to say, i paid my minimum 15% based on the food cost and will never come back anymore. read more

Restaurant Yamaguchi is always such a treat. The sushi was super fresh and the staff is very helpful and polite. We ordered the tempura as a starter and it was very light and crispy. We also ordered the sushi sashimi and the fish was very fresh. It was a great variety and I was able to try a bunch of sushi. read more

Best sushi restaurant in Long Island. I enjoyed eating here and service always good. I will recommend this restaurant to all my friends.

Yamagushi has always been authentic.Service is good.Ambience is modern. I miss the warm welcome of original owners.

Under new ownership - not as good as it used to be. Salmon sushi had a thin white layer on the side (don't even know what to call it). Shrimps had a black spot on the tail (don't know what that's about). We miss the prior owners very much as they knew how to prepare authentic high quality Japanese foods. What a disappointment! read more

I am not impressed with this restaurant due to different management. I was hearing the workers were speaking in chinese. So I found out the original owners retired. The service is pretty terrible because I hate the rushed service especially the amount we spent there. We both had the omakase dish, it was good but they pretty much kicked us out in 30 minutes. The authenticity of this place was what made this place great but now it is just every other japanese restaurant that are owned by chinese people all over long island. I was also still hungry when I left, so yeah it is a bit overpriced for what you get. read more

Under new ownership, Yamaguchi used to be the only authentic Japanese food in town. Now, the food here is barely edible. Do not order anything other than sushi. The kitchen menu tastes horrible, and the servers don't even know what's on the menu. I've been coming here for 15+ years, but I won't be revisiting. read more

Probably one of the two best sushi restaurants in Port Washington. Fish is super fresh and the rice is cooked just right. Their fish really melts in your mouth. Omakase is very much worth the price and the dinner sushi sashimi combo is an excellent choice that won't set you back as much. Overall, the food quality is A+. But the take out service is abysmal. Once quoted 40 min wait that turned into a 75 min wait. Once called and then the lady just left the phone. So if you're wondering why there's almost always a busy signal, it might be because she picks up the phone and then just leaves it there?!! If they can get the service together, this place would be a five star restaurant. That said, given that this is still my top 2 favorite sushi restaurants in not just Port, but all of Nassau County, I'll keep going because the food really is THAT good. read more

Wonderful local place right off the main streets of Port Washington! The waitstaff were kind--a bunch of very nice ladies. Lots of great Japanese food options depending on your mood. Speaking of mood, the atmosphere is so friendly, quiet, family-friendly. You can come here like I did with a party of three to eat casually, ordering a small selection of sashimi, rolls, appetizer, and soba noodles. There are also fancier items on the menu. The sashimi selection was fresh and delicious, with a nice choice of salmon, tuna, white tuna, yellowtail, and others. I spotted on the menu there is an omakase option ($65), so I hope to come back here next time to celebrate. Would recommend, stop by and enjoy Yamaguchi and all it has to offer! read more

Kids craving for Japanese food so we come here to try. Food is pretty good and authentic. It's owned by a Japanese husband and wife couple for many years.

Price is only half compared to other sushi places in Manhattan with the same quality. Whenever we want fresh and decent raw fish, we come here. Never feel disappointed! The kitchen food are good too. My son had karikatsu (fried chicken cutlet) tonight. We thought it might be dry and hard, but it came out juicy and perfect. For families with kids, this is definitely the best place where everyone can find tasty cooked or raw food. read more

Several friends recommended this place to me so you know I had to try it for myself. Group of us with kids really enjoyed the food. Wait staff spoke Chinese which was helpful. The kids couldn't get enough of the Hamachi Kama. Only downside was that the food took too long to come out. But that's because the sushi chef was the male owner, which may be on the good side. Finally sushi by a Japanese chef. Authentic--the rice didn't separate from the fish, even after biting just a portion off. And the wasabi was gourmet. read more

They have new boss and menu. Though most items are kept on the new menu, quality went down. Sashimi is not as fresh, tempura batter is thick and greasy. We ordered udon and that is the biggest disappointment. They use thin flat noodles instead of udon. There is nothing in the broth, not even a few scallion pieces. It's the worst udon I ever have. We have been coming for years and always enjoyed their authentic cooking. Hope the new boss will save this place. It's quite sad to give up a long time beloved cuisine. read more
