Good food and service. First time trying korean sushi. Ambiance was traditional and nice.

This place is super good and the food here is super delicious! Also, the service here was really nice and the food came quickly.

Was exited to try a new place. Ordered lobster soup. Came with two claws. No tasted at all. Also came with the head which was empty. So was exited about the soup broth. But it tasted like dirty sink water. Tempera was good. Albacore sashimi was good but extremely small portion. Will never come back read more

Unbelievable amount of food for the sushi dinner. All top quality along with the service. The sushi chefs were great! Would definitely return. read more

Yikes- has anyone seen a piece of salmon this small? I thought it was a mistake. But all 3 salmon bento boxes look like this. My 1 year old niece ate this entire piece herself. We are all looking to make a second meal right now. read more

Wanted sushi for a light lunch--ordered 5 rolls of 8 pieces each for a family of 4, and Man Sun definitely hit the spot in terms of fulfilling a sushi craving. Our favorite was the scallop roll and the rainbow roll--the fish was fresh and tasty! However, there were a couple of rolls that were quite tiny with mostly rice and when we got takeout, there wasn't any soy sauce which was somewhat surprising. Would come back to perhaps try their sashimi! read more

This place is a hidden gem! The food is simply delicious and savory. I loved each dish given and the side dishes complimented each of them. The uni presentation is also phenomenal and pretty. Because the uni was slightly small, they gave us two in order to compensate for that which is super nice. The staff was kind and friendly to my cousin and I as well! Definitely recommend! read more

On Mother's day, we arrived at this place after a failed experience at another restaurant. Thank God this place saved our Mother's day! It wasn't busy on a Sunday lunch. The staffs are nice and responsive. The lady even gave my kids some toys! The abalone porridge was amazing! The sashimi was ok. Seafood udon was great value. Complimentary ice-cream comes at the end. Overall I think their Korean dishes are better than their Japanese dishes. I highly recommend to try this place if you haven't yet. Bring your kids too and they will get toys! read more

The place deserves 5 star, very friendly service, big portion, a nice mix between Korean and Japanese cuisine.

WE love us some Man Sun, good portion, tasty food and nice people. It is easy to find and this location has been around for years, but changed hands many times. the current owner does a great job for a local sushi joint. read more

quality food and very kind service:) you are greeted as soon as you come through the doors^^ once you are finished, you are given a complimentary green tea ice cream to end your meal:3 i've come multiple times and i consistently have good experiences. read more

The prices are real good. Whoever said it was pricey must be an AYCE person. Service is fantastic. And most importantly the fish was fresh. I really enjoyed this place. I will definitely be coming back for lunch as their lunch specials look really good. Someone said you get a good amount of food for the price. read more

So good that we're coming back a second night. If you're in Diamond Bar, this would be a good restaurant to eat sushi because: 1 - service is good unlike the one by Walmart; and 2 - the food is traditional, their miso soups doesn't have zucchini unlike the restaurant by Albertsons. Parking is mostly on the street. read more

We got some large combo to share with 6 people. The sushi and the teriyaki chicken were pretty good, but I wish the side dishes they gave out were optional. A handful of us didn't enjoy the side dishes as much and I thought it was a waste to give the sides out to people who most likely wouldn't eat it. It's probably be a good idea to confirm with people who ordered if the side dishes as they are would be something they'd like or if they can swap them out with something else. The sushi was super fresh and I love the rolls they had as well. The takeout experience was also great with all the necessary utensils and sauces. The sushi presentation was also pretty beautiful. read more

It's a family style restaurant, cozy not too crowded. We have sat in a small room for the dinner last week. They have lots of small snacks dishes, so you might not need to order a lot. Food is delicious and nice. read more

Mansun Sushi - Japanese Near Me - Walnut, California

One of our local go-to spots for Korean style sushi. You won't find the highest quality fish here, but you get other perks - free banchan, other Korean menu items (the daegu tang is a fave), and the ever-friendly owner who always brings a smile. The uni bowl is always delicious, although somewhat small (because of the single serving of uni) that disappears so quickly! I like the sushi/sashimi combos that comes with rolls and tempura. We always leave here feeling full and happy. read more

Always like trying new places, but this wasn't as I was expecting, unfortunately. I ordered to go, the lunch box. The chicken was a bit dry and everywhere else I go they put teriyaki sauce on top but they didn't .The rolls were tiny and weren't good. . I gave 3 stars because the woman that greeted me was very nice. Overall the food was not satisfying. read more

Amazing place to eat so fresh and every thing was sooooo good would recommend and also good with kids :) read more

This is the worst udon I have ever had in my life. It looks like the chef forgot about it in the pot. The noodles were so overcooked that they were falling apart, and I could barely pick them up with my chopsticks. The tempura was cold and unevenly battered; one was falling apart. I cannot believe they spooned this into a bowl and served it. Slow service due to short staff I can understand -- but this chef clearly has no pride in the food they serve. read more

Oh my gosh I did not want to review this place like this because this was my all time favorite place to eat at when in Los Angeles for the price and value that is given. If you were a seafood lover this was the spot... I don't live in Los Angeles but in a land far far away and so this was always a special treat from... So to start the special is now 60 bucks which is ok I don't mind but the food quality sucks... the special is what you always order here and the chef have never gone wrong... sushi was definitely fishy... the once lobster sashimi is now gone... there was no salmon head but replaced with two mackerels... one good the other firm and chewy... lol not sure if they were show casing the two different types? One edible one inedible... Ok the saving grace for this meal is there is an in and out burger right across the street... we are heading there right now to eat... Sadly after 7 years and at least 9 trips here this disappointment does not even begin to describe how sad I am about this place... The people/owner and servers are nice... no knock there... just sad about the food quality... this place was so good... I'll try again in a few years if only reviews get better... read more

If you're looking for a place that continually forgets portions of your order, you've come to the right place. I can totally empathize if it were extremely busy but we we're 1 of 2 tables. Thank you but no thank you. read more

I absolutely loved their "banchan" side dishes. I ordered a sashimi salad and was surprised by the array. It's a good lunch value and I hope to pass through this area again soon. read more

Like some other reviews have said, this place has fallen behind...so much. Prices increased. Inversely, the quality decreased. I have no issues paying more if the quality is maintained, but this is a no-go. This used to be a special place for me and my family. In the past and for years, we'd come here for special occasions and since the state "fully opened" up again, we decided to come here for dinner to "celebrate." My mom and I came here for dinner and we paid $90 for the medium sashimi combo, walked out paying $115+ with tip and tax. We would've been more satisfied if we went to a AYCE sushi place at $40/person. I remember I could've walked out in the past paying around $150 and that was good for 4 people. The price we paid our last visit left us barely stuffed. Their signature sashimi combo is a shadow of its former self. They got rid of signature highlight dishes with much lower quality replacements. The starting sashimi salad was replaced with soba noodles with a gochujang sauce. I think this was done on purpose to stuff you with carbs from the get-go so you don't notice you're getting less food. There's no longer a lobster sashimi where they'll use the shell to make a soup at the end. There was noticeably less sashimi too. I mean you can pack the plate with as much of the string daikon as you'd want to make it look impressive, but it's all just looks. The uni bowl was replaced with a very mini unagi bowl. Two small paltry pieces of unagi that replaced what used to be a whole sea urchin/uni. They ended it all with a maeun-tang (spicy fish stew). And holy crap..more like spicy fish bone soup. I was lucky I didn't choke on a bone. There were fish bones in almost every single sip. Even my mom who is usually fine with fish bones. To top this low quality soup was the paltry amount of other ingredients. There were just 2-3 small pieces of radish that looks more like garnish than being a part of the soup and enough enoki for just one person. You know how you can get a bag at the market for like $2? Imagine that bag, but split among 10-12 people. That's how much enoki you got. We left fairly disappointed. I had doubts about the recent reviews and we wanted to try it out to see for ourselves. We'll have to look for a new replacement restaurant for family occasions... read more

I didn't know what to expect because most of my best Korean food experiences while in LA has been in KTown; no brainer right? ;) But this place that isn't too visible (we drove by it twice), was actually quite surprising. Service was great and the portions were plenty. I'm definitely going back again soon. The sea urchin unni rice mix as part of the multi course set we got was delicious. It was larger than most other restaurants too. read more

I always love their place. Good food and nice price. Very affordable for high quality of food

Based on the high YELP reviews we were super excited to try their food. What a disappointment. We ordered sushi which was mostly rice and not so fresh fish. The lobster soup was not at all appetizing and I wish I knew what to order to get actual lobster. The broth was like dirty fish water. We will not be returning. read more

Man Sun, you tricked me into ordering your delicious looking uni bowl and instead gave me a mediocre rice bowl that doesn't even have sashimi in it! Since my friend loves uni, I decided on this place since I've been eyeing their uni bowl for a while now. We both got the UNI BOWL (off menu), but it was really nothing special. It only comes with a few pieces of uni, seaweed salad, assortment of seafood, but no sashimi. I thought it was their take on a chirashi bowl, but I guess it's nothing like that. They also serve banchan, and I hate to say it, but their banchan was better than the uni bowl. My friend had to order two more rounds of nigiri because he wasn't full from the uni bowl. In the end, they did offer complimentary green tea ice cream though, which I appreciated. Tip: This place is also super hard to find. Turns out this place is right next to the liquor store and facing the street, so you got to either street park or park in the tiny parking lot by the dentist or the farmers market. read more

Avoid this place!!! My whole family got food poisoning after eating at this place during the Labor Day weekend. We ordered the big sashimi platter and uni bowls and the quality of the food was just bad. Sashimi and the uni bowls were not fresh and everything smelled fishy. My parents had to go to the ER for food poisoning.. please avoid this place for the sake of your health. read more

It's a small little place inside with a spare room to the right. It's a little pricey here not so much for the lunch menu. But they give you a lot of food. His and her bathrooms pretty clean. They took care of us the minute we walked in the door great service. The only thing I have is the parking situation there's no real lot for this business. It's street parking or a dinky little parking lot that is about five cars. Bon Appetit hope you get to try it out. read more

Mansun Sushi - Wow they put a lot of stuff. Kimchi I don't eat. I had a bad reaction to. Small salad rice - Japanese Near Me - Walnut, California

Went here a while back because my friend was craving sea urchin bowls Let's get into the review. Layout: The restaurant is small and the parking is weird. You have to walk around it to get into it. I was placed into the seat where the sun was hitting my back. What I ordered: Sea urchin bowl! Also came with sides. Food: It was a new experience because my previous instances from having sea urchin was only from all you can eat sushi, served as nigiri. The side dish I ordered came with a garnish, and my dumb self decided to eat the garnish. Yeah oops my bad! It was a funny story to tell though. To describe the taste of the sea urchin, I would say something like it tastes fishy. It's not easy to describe it but that's honestly the best I've got. Th representation for the food are phenomenal. Service: Average standard. Price: Surprisingly affordable. Recommendations: I recommend this if you're in the area and want to make a quick stop if you are craving uni. The presentation is very phenomenal. read more

Get the Man Sun Special Combo for $45 and eat like a king. Dish after dish kept rolling out from the kitchen, I couldn't help but laugh after we ran out of room on our table. I really came for the uni but was told their supplier had a temporary shortage. Was extremely disappointed but our waitress threw in some extra items to make up for it. Highlights ---------------- Porridge -- The porridge was plain but they definitely added some seasonings to it because it was clearly more flavorful than a bland porridge. Ultra thick consistency with just a hint of sweetness from the rice. What an excellent 1st course! Sashimi Platter -- A massive plate overloaded with sashimi. We're talking cuts of fatty tuna, salmon, yellowtail, red snapper and lobster. The tuna was incredibly soft but the salmon seemed to have a thin layer of gooey film. The lobster was unbelievably sweet, tastes just like how it is steamed but with a softer, wet texture. Lobster Soup -- They take the head from the sashimi platter and cook it in the soup to give it that distinct flavor. The soup comes with an assortment of vegetables but the flavor from the lobster is really what makes it. It's the last course of your meal, which is great for the tummy. The restaurant gets especially packed for dinner so make sure you get there early. I hear the Asian buses like to stop here because of the famous special combo. I'll have to come back to try the infamous uni bowl. read more
