Mansun Japanese Restaurant

Wonderful food and very friendly staff

Fresh sushi and delicious rolls make this a place where happiness is always on the menu.

Freshest sushi around area. Will go back soon

Fantastic sushi. The staff were very friendly to the table.

I always feel rushed. And maybe it's a culture thing. But I never feel welcome. Food is good, though.

Man Sun Sushi is a gem! The quality of the sushi here is outstanding – everything is fresh, beautifully prepared, and full of flavor. From classic rolls to creative chef specials, every dish feels thoughtfully crafted. The sashimi is melt-in-your-mouth tender, and the presentation is always impressive. The ambiance is warm and inviting, making it a perfect spot for both casual lunches and special dinners. The staff is friendly and attentive, ensuring you have a great dining experience. If you’re a sushi lover, Man Sun Sushi is a must-visit!

Everything is great. We came here for a birthday meal today. There were not many people on Monday night. The proprietress and staff were very enthusiastic and concerned about our dining situation at any time, and would also recommend ways to order more cost-effective meals. I saw some reviews saying it's not new, but we haven't encountered this at all. The food is fresh and delicious, highly recommended!

Esther Ajumma is wonderful! They have a set sashimi dinner menu. Priced per person. So much food, well worth the price. You have to come here and eat! A small quaint place with really good food.

If you're in Diamond Bar and craving sushi, ManSun is the place to be. Forget the stellar service and welcoming atmosphere—although both are exceptional. The real star here is the food, with some of the best sushi around, fresh and expertly prepared. And don't skip the post-meal ice cream! The strawberry and green tea flavors are must-tries. If you're in the area, do yourself a favor and stop by. You won't regret it!

My wife, son and myself went overthere to celebratey 72 birthday. This was on Tuesday 20, 2024. I decided to try the urchin and fish eggs cause I used to eat that back in Chile many years ago. To make the story short the three of us got very sick. The same night I got diarrhea, then my wife and son got diarrhea and vomit the next day. That was really upsetting. The food tasted fine but was a terrible disappointment. May they don't have enough hygiene in the kitchen to prepare food.

Great mom & pop restaurant. Food is delicious.

Their uni tastes extremely bitter, although looks nice on the photo. From my experience, they must have used alum to store it.
Their sashimi and other things are
