    I've been coming to this gem for over 20 years! The lady owner is always incredibly welcoming and hospitable. Even with inflation hitting hard lately, you can still feel their sincerity in every dish. The portions are huge, and the sashimi is sliced generously thick! What touched us the most was when we mentioned how much we loved the tea, the owner immediately gave us a bunch of roasted rice (Genmai) so we could brew it ourselves! The interior is always cozy and spotless. It's rare to find a place that maintains this level of quality and warmth for decades. Highly recommended!

    I love this place, the woman who works here is so friendly and nice. Me and my family came here for a birthday and they made it really special. The sea urchin bowl is really good and unique. The sushi boat as well. And the lobster seafood hotpot. It is casual but I think because of the staff it is special. Would recommend!

    I thought I would update my review from before since it's been a few years and am sad to report that it has gone downhill. I know times may be tough, but yikes! BROILED SALMON & MIXED TEMPURA BENTO BOX: I ordered this to go and it came with a scoop of rice, 4 spicy tuna cut rolls (used to be 6), a small clump of salad, tempura (came without the tempura sauce), miso soup, and the saddest/hardest clump of fried/broiled salmon (came with side of teriyaki sauce). The portion has SIGNIFICANTLY shrunk especially for the salmon. The salmon was basically the size of the sauce dish container...I finished it in 2-3 bites. Due to this, I will sadly not be returning.

    Great quality sushi in a friendly mom and pop restaurant! The restaurant itself is very cozy, limited seating but luckily on a Tuesday evening, there was no wait. Small private parking lot adjacent to the restaurant was convenient! The meal starts with complimentary salad, miso soup, and edamame. These were a nice surprise! We then went on to the fried calamari and baked mussels. Calarami was nice and perfectly crispy with a drizzle of a sweet sauce, it was perfect to share amongst three people. The baked mussels were amazing!! Topped with cheese, a sweet and savory sauce, the mussels were juicy boys and definitely got us excited for our main sushi entrees! We went with the albacore roll, spicy tuna roll, eel sashimi, salmon roe sashimi, dragon roll, and yellow tail sashimi. Initial impressions - great presentation, and came out relatively quick! The sashimi was FRESH, and the perfect amount of rice. I dislike when there's any more than a pinch of rice and Mansun did the portions just right! The salmon roe was a generous portion, and with each bite, they popped heavenly in my mouth. The rolls were meticulously made as well and tasted amazing! For the three of us, I think we did well with the portions and by the end, felt quite satisfied... This is when the waitress offered complimentary ice cream! How could we say no...so we all decided on the green tea ice cream. It wasn't too sweet, and was the story book ending to our meal. They do offer bento box style meals with tempura as lunch and dinner specials as well, so in the future I'd absolutely like to try these out! Overall, highly recommend and will definitely be back. Don't let the unassuming exterior appearance of the plaza dissuade you from giving Mansun a try!

    Esther was an amazing server for my friends bday dinner! The food was so good , she was so friendly and funny. Made us feel like family! We had a private room that was great for an intimate bday setting.

    This place was amazing. Our server was very quick and sweet. As teens we normally don't expect such great service but everyone in the restaurant had positive energy and was very efficient. Along with this the food was great.

    The food is always so good here! The sashimi is fresh and the uni bowl was soo flavorful and yummy. I came with my boyfriend and the sushi chef was sweet and made us the most adorable swan couple out of an apple. The owner is a nice Korean lady who has the nicest smile. Service is 10/10 and the food is also a 10/10! I highly recommend this place especially if you like uni!

    I can't believe I've been driving by this place for years without stopping in--what a hidden gem! The food here is absolutely amazing and unbelievably fresh. The fish quality blew me away--so high-grade, so clean-tasting, and not fishy at all. I was genuinely surprised at just how good everything was. I tried the sea urchin bowl, which was insanely fresh and flavorful, and the lunch special teriyaki chicken with tempura--the portions were very generous and satisfying. I also ordered the sushi lunch special, and honestly, the fish quality was mind-blowing. It felt like something you'd expect at a high-end sushi spot, not a casual place you just stumble into. On top of the food, the service was excellent. The owner is so kind and welcoming, and they even give out free ice cream at the end, which was such a nice touch. It really feels good supporting a local small business when the experience is this good. (5/5) -- Fresh, delicious, generous portions, and amazing service. I'll definitely be coming back again and again.

    Sea Urchin

    Ordered to-go around 11:40 a.m. on Sunday. Food came out fast and was nicely packed. Few sea urchin spines were mixed into the rice, which was a little disappointing, but everything else was fine. Side dishes were light and tasty. Regular size was $33 (large $44 with tax). I'll probably go for the large next time--it was better on my last visit.

    My go to spot for sushi in the Diamond Bar area! In my opinion they have the best combination of quality, price, and service. The owner/lady in charge is super nice and provides great recommendations, and the sides come quickly when you sit down. One of my favorite things about this place is the Banchan they provide since it's Korean owned. The place itself is small and cozy and really never too crowded so you can get seated quickly. Great place for casual dinners as well as celebrations (love their sushi boat, it's a great deal)

    對生命而言,接受才是最善待自己的方式,無論是接受一個人的出現,還是接受一個人的再也不會出現~ 滿船, 一家也開好久老店了, 韓國人的日本料理, 就是會澎湃到讓你吃不下, 但品質跟日本師傅開的就是不一樣,他家最有名的應該是大家都熟知的海膽飯, 現在是29 元一份, 朋友點了他們的sashimi 全餐, XL 的,滿桌的東西, 讓我有點嚇到, 也太多太多了吧, 如果你是只喜歡吃正宗的日本師傅做的生魚片, 這家不用來了, 但如果不是嘴巴很挑的歪嘴雞,是喜歡俗又大碗, 划算的吃法,這家是選擇之一, 我記得他們以前生意超好的, 這次去還行, 不過沒有那麼熱鬧滾滾是真的了!

    A small and unassuming restaurant located in Diamond Bar. We came on a Friday afternoon shortly…read moreafter opening and the restaurant was already quite busy with a wait of about 20 minutes. I ordered their "Sushi and Sashimi Combination" from their Lunch Special menu which came with 6 pieces of sushi, sashimi and a half order of a tuna cut roll. The combination plate is very reasonably priced especially for the quality of fish which was fresh and delicious. The lunch special combo also comes with a bowl of miso soup and salad so you definitely get good value for the price. Service is standard, and there is a decent amount parking within the plaza.

    I'm honestly really disappointed with my experience at Makomae…read more We were seated for about 15 minutes and no one even brought us water. We tried waving at our server multiple times, but she just kept ignoring us. Meanwhile, other tables who were seated after us were already getting their drinks and food. There are only about 7 tables and 3 servers, so it really shouldn't be this difficult to at least serve water. I eventually had to walk to the kitchen myself just to ask for it. Even then, no one came to check on us for another 10 minutes. When the server finally took our order, we politely asked why it took so long and why other tables were being served before us. She completely ignored the question and didn't respond at all, the attitude was incredibly rude. This level of service is unacceptable. I will not be coming back.

Huge thank you to Yumi, who was an absolute angel and made us feel so welcome (like we were her grandchildren and wanted us to stay). The food was genuinely great quality and the portions were way more filling than expected. At first, I thought we hadn't ordered enough and i was mentally prepared to order more... but by the end, we were so full. Truly a lovely experience. They also give you complimentary edamame and cucumber salad, which was such a nice little bonus before the main event. One of my friends ordered the chirashi bowl and it looked like a bouquet of all kinds of fish. We also got the chef's assorted sashimi (amazing assortment) the ankimo special (SO good), and the 4 piece hand roll special (could probably skip this one and save stomach space). For nigiri, we ordered uni, toro, tai, and yellowtail (all amazing.) The uni was especially creamy and delicious. The salmon belly was mesmerizing, the yellowtail belly melts in your mouth and did I mention the ankimo? We also ordered a fish only tempura, and they even gave us our own tempura dipping sauce. It's the small details like that that really make a difference. 10/10, come hungry, leave very full and slightly emotionally attached.

This time, I tried the omurice, which is egg-wrapped, curry-flavored rice and chicken with your choice of sauce. I chose their curry, which I've always enjoyed. This also came with your choice of corn or miso soup and a salad. I also ordered a side topping of sautéed chicken as I was especially hungry that morning. The omelet wrapping the rice was nicely fluffy with a deliciously subtle blend of savory and sweet flavors. I enjoyed the diverse spices from the curry-flavored rice. With small chunks of chicken, the dish was slightly more filling. I wish there was just a little more curry portioned out. The sautéed chicken on the side was delicious and reminded me of times I enjoyed pan-fried steak dishes from Hong Kong cafes. Interestingly, the omurice came with seasoned fries and steamed carrots and green beans a slight touch of American cuisine). Overall, it was delicious combining all the flavors from the curry, rice, omelet, and sautéed chicken into one bite. Service was good. All our dishes had a nice and careful presentation. Our server also refilled my water without me asking. However, the restaurant can get loud due to the small interior. As usual, parking was in high demand, but we found a spot close to the north exit. There was a crowd of people standing near the entrance, so I thought we were in for a long wait. However, they were thankfully waiting for another restaurant nearby.
