The staff is very attentive, and the sushi is excellent, though a bit on the pricey side. It's easily one of the best sushi spots in the OC, and definitely the top choice in Orange. The place is small, so to guarantee a table, I recommend arriving right when they open.

Solid solid sushi located in a non-descript strip mall. Don't judge a book by its cover - what's inside is a quaint, clean sushi bar/restaurant. We had the omakase during our visit and was not disappointed! Whenever we're back in the area, we will be stopping by again!

Best sushi I've had. But it's priced accordingly. Look to spend around $100 for omakase and a beer with tax and tip included. I've been here a half dozen times. Service is very good. They are smiling, attentive and consistent. Ambiance was a nice little local spot. Need to make reservations so you don't have to wait an hour. But if you're a lot for a quick lunch, the bar is great for omakase. The chefs are so skillful. The sushi is something you'll talk about to all your friends. But please don't go here, the wait is too long already haha

This place is sooooooo good and needs to be gate kept but I can't help it I'm sorry gotta share the love! You need to wait in line before it opens to put your name down for a table at the bar! But it's so worth it. Went for my birthday and did the omakase, with star pieces like the bluefin, amberjack, cherry salmon, and the black cod.... Those elevate you into another dimensions, and all others are great pieces of fish! Although there's a decent amount of space, it's full the entire night! So just make sure to plan your dining experience accordingly. You might get lucky if you can call right when they open too for a reservation

I was so excited to try this restaurant because it was rated one of the best. However, it wasn't as good as I thought it would be. The sashimi and nigiri were BOMB. All the fish served were good sizes, which we appreciated. We didn't choose the omakase so maybe next time, I'll do that. The shrimp tempura was sooooooo good. Omg. Anyway, here are the things we ordered: Black cod nigiri Bluefin tuna nigiri Tuna nigiri Lobster hand roll Salmon skin hand roll Blue crab hand roll Spicy tuna hand roll Shrimp tempura Negamaki Agedashi tofu - I've had better ones :/ Braised pork belly Miso duck with forbidden rice The rolls and sushi that we tried were great. However, the hot dishes that we ordered lacked flavor, in my opinion. Service, however, was great! The hospitality they showed us was appreciated. This location is in a plaza so there is ample parking. I think it's best to make a reservation rather than to walk-in. Unfortunately, they do not do reservations online - you have to call them. Details about our dinner: - reservations for 3 at 5:30PM on a Wednesday

I've been to Ohshima many times before but ever since the business has changed hands I started noticing a change in my overall experience. Food quality is still high but feel a bit different than my previous experience. I had a selection of nigiri sushi and handrolls. For sushi, I ordered Amberjack, Salmon, and Aburi Engawa. While I do enjoy scores on the surface of the fish (helps give that melty experience when you eat it), I do think that the salmon was cored too much. The aburi engawa was very tasty though. Overall, the ratio of fish to rice also feels a bit off. While I do like having more fish than rice, it feels like there isn't enough rice per sushi to make the sushi balance. The Blue Crab Handroll and California Handroll were very good and so are the other hot dishes they offer on their menu. The ambiance is still the same and I think the service is the same if not a little better than before in terms of the staff's attentiveness. They have also opened up more restaurant hours so people can dine here at lunch instead of waiting in a long line for dinner. Altogether, the experience was good and I might be just being picky about how my meal went. This place is still a great choice to dine at if you haven't been here before (but if you've been to Ohshima, you'll get where I'm coming from).

Been wanting to try out this place for so many years now because of the good reviews but was so hard to make reservations then. Today is my 9 year bf/gf anniversary with my now husband and really wanted to eat sushi. Called yesterday - Friday after 6 PM, got through after the second call and was able to get reservations. We were definitely excited about it. Came 15 minutes before our 6:15 PM reservation and was seated right away, the restaurant was half empty with a nice quiet ambience. We sat at the sushi bar which i love because we enjoy watching our food being made. Our sushi chef was very nice with our small talks each time he handed out a nigiri. We did the 10 pc Omakase ($70/pp) and added 4 more nigiris ($68) after. Every single one was different in taste and texture - we were very pleased with the quality of the fish and the warmth of the rice. Uni is always my all time fave and Toro is never a bad idea either it just melts in your mouth! We wish our dinner didn't end but we came still a bit full from a lunch party. We'd love to try their Uni pasta next time!

Very legit sushi place. Miso Duck is very good! Fatty and chewy. I'm pretty okay with wasabi, but there is WAY too much wasabi for the scallop and Sea Bass. Everything else was perfect. Shrimp is very good, choose the fried option! Recommend asking all the prices first thats not written on paper.
