If you're looking for a late-night, all-you-can-eat sushi spot, Ozen Sushi is definitely worth checking out! Their AYCE menu has an impressive variety, especially when it comes to specialty rolls and fresh sashimi! Ozen offers creative rolls packed with flavor and thoughtful combinations that keep every round exciting. They are generous with their fish portions, and each bite feels so fresh! My favorite had to be their "Tataki Roll," which was packed with spicy tuna and jalapeño, and their lineup of fresh sashimi options. read more

Being from the bay, it's always nice to have so many AYCE sushi options when visiting Southern California. This time, it was Ozen. To be honest, Ozen wasn't the most impressive, but wasn't bad. While there was a heavy focus on rolls, you still had your sashimi options and picks. You had your appetizers, noodles, etc... I liked the smaller sashimi pieces, but the service was a bit slow even though we were the only table for a while. The location inside was very small. Much smaller than I had anticipated. There is an outdoor seating area and with Ozen closing at 2am, I can see how the outdoors become popping. Three parking spots in the front and a number of parking spots in the rear. Oh, there is a 3% surcharge for credit card usage. It is on the menu. read more

This was our first time visiting Ozen Sushi. We didn't do the all-you-can-eat option this time and ordered a few sushi rolls and a bento box instead. The food was okay--nothing really stood out, rolls were similar to what they have at other places. The service was good, and the staff was friendly throughout our visit. It seemed like they might have been a little short-staffed because there were quite a few open tables, but we still had to wait a few minutes before being seated. The restaurant offers both indoor and outdoor seating, which is nice, and there's plenty of parking available in the back, making it easy to find a spot. Overall, it was a decent first visit. I may come back in the future to give their all-you-can-eat menu a try since that seems to be what many people come for. read more

Came here previously, portion sizes were small and service was slow. Had to wait about 20+ min for the food to arrive at the table. Came again on a Thursday evening. Over half the restaurant had empty tables. There was a party of 4 and a party of 2 ahead of us. I was also a party of 2. It was NOT busy at all. We waited 15ish minutes and ended up leaving. We looked inside and it looked like there was only 1 server working. read more

This will be a perfect sushi spot if the service wasnt so rude. Let's talk about the food. The food is amazing. The sushi is such good quality and you can tell that it's very fresh. I am a fan of that. They also do have hand rolls, which is not common at an All You can eat restaurant. The miso soup, the cheese, corn, and the tuna cracker were all phenomenal as well. I will say the portion on the fried appetizers were hilarious. On the menu is states that one serving of eggrolls is (2), so since it was only two of us, we thought one full egg roll each. It was actually just one piece cut into a half which that pretty funny. The shrimp shuamei is not very traditional, they were fried and kind of burnt, but it's OK at least they were crispy. The stars of the meal with definitely the sushi. We love the late hours and all you can eat and it's pretty big so the waiting time is usually small. However the servers always so rude when you come. The host was really rude while leading us to our table, and it took forever for someone to come around to start taking our orders. We actually waited 15 minutes until I flagged someone down. It wasn't until one female worker who came later on that we started experiencing good service, you're the owner and you're reading this please let her know that she's doing an amazing job and the rest of the male staff that night is not. The restaurant is well kept nice and clean plenty of room and is playing good music! read more

Very disappointed we came from fresno visiting family here and was excited to try some good sushi from a place with good reviews. They kept giving us the wrong order and they also took forever to give us our food when there was only about 4 people in here. There was flys and Nats flying everywhere. Very unclean there was trash all over the floor under tables and in the walk ways. Definitely will not be coming back and definitely won't be recommending anybody to come here. read more

With a wide variety of high-quality rolls, nigiri, sashimi, appetizers, and more, there's something for everyone with the AYCE option. Their nigiri had an ideal fish-to-rice ratio so we could enjoy all their sushi without feeling too full. A great place to bring your friends and family or for a quick bite with non-ayce menu options. They're also open until 2 am for late-night sushi cravings! read more

Can't believe I just recently found out about an AYCE sushi spot that stays open this late! If you're a night owl and like to avoid the main dinner crowds, this is definitely a spot for you to check out. We got here around 10, and there was still a pretty good amount of customers in the restaurant. The server was nice and attentive, and the food came out pretty quick. The nigiri was really fresh, and I really liked their spicy tuna. Definitely a good option for a late night big meal that doesn't feel super heavy. There's a good amount of seating, both inside and in an outdoor patio, and there is a sizeable parking lot in the back as well. I'll definitely be back here whenever I have some late night sushi cravings! read more

Dry old sushi. Flavorless sushi rice. A staff that seems to know nothing about customer service nor sushi. I would be much happier eating sushi from a grocery store, where it's fresh. This place should only be visited by drunks at 1am. The ambiance is good if you like raider fans. read more

First Impression: late night sushi is the best - and to find a place open after 9pm is rare! Location: Right off the main road, if you don't pay attention you'll miss the turn. More parking is located in the back. Experience: They have indoor and outdoor seating; but no bar seating. We put our name on the list and were seated within 20 mins. The menu has a variety of sashimi, sushi, apps, and rolls. The carpaccio options are my favorite! Especially paired with a cucumber roll. Note: none read more

We stopped by here last year on our Disneyland trip and had AYCE. I loved that they didn't make us pay for AYCE for my kids who don't eat sushi at all. The kids only wanted a bowl of ramen. We usually have to avoid going to AYCE restaurants with the kids for this reason because they never eat the food. This was some of the best quality AYCE sushi we have ever had. We loved the mackerel and the seared salmon. Yum! Can't wait to come back again on our next visit. I really hope they keep their policy and don't force the AYCE charges on children at the table and continue to allow a la carte ordering for them. I really loved having this option. I was also shocked by their hours...AYCE sushi and they're open until 2am?! Sign me up!!! Too bad this place isn't closer to home or I'd be a regular here. read more

I'd say I come to Ozen at least twice a month and have never had a bad experience. Their service is great, they are constantly checking on how we're doing and if we need anything else. The food is amazing, we will always get the all you can eat option. Our favorites are seared salmon, salmon, & baked mussels but as you can see from the photos everything is delicious! I think their rice to sushi ratio is great! read more

We were regular visitors when this was Hai Sushi and thought we would give the new place a try even though we were used to all you can eat. We are now regulars here! The rolls are excellent. In our opinion everything is fresh and very tasty! We highly recommend coming in and giving the new owner, Eric a try! Thank you! read more

My fiance and I came for dinner tonight. Overall, the experience was fine. I would describe it as unremarkable. We got the premium menu which was $47.99 a person. We tried a bunch of different items on the menu and most of which was good! However, there were a few things that were subpar: - Rice itself was dry. - a couple items we ordered never came out - it took a while for our server to check on us That being said, there were some positives! - Miso soup was warm and very tasty - Tempura was crispy and lightly fried! Very nice - restaurant was clean, albeit untidy with boxes and various inventory on the floor. Long story short, we probably won't come back. For $116, this dinner was not worth it in terms of quality of food or service. 5/10 Nothing special. read more

Ozen Sushi - Japanese Near Me - Buena Park, California

This was hands down the worst dining experience ever. The food quality, service, and management were all abysmal. First, I found a dead fly stuck to my tuna sushi. When I complained, the male server didn't even apologize. Instead, he used his own chopsticks to pick up the contaminated sushi, replaced it with a single piece, and walked away without saying a word. The food itself is a scam. The "$15 Spicy Tonkotsu Ramen" is nothing more than a $2 instant noodle pack from a Korean grocery store with pieces of chashu thrown on top. The salmon belly sushi was spoiled; I had to spit it out immediately. Since eating here, I have had to use the bathroom four times in just three hours. To make matters worse, I requested the bill before we even finished our first round of All-You-Can-Eat. I noticed a "POS Provider Fee" added to the total. There was zero mention of this hidden fee on the menu or anywhere in the restaurant. Does management not know that charging undisclosed hidden fees is illegal? When I questioned it, they said they would waive the fee only if I paid in CASH. I hope they aren't trying to play games with Uncle Sam. Please check your bills carefully. This place is unsanitary, unprofessional, and deceptive. SAVE YOUR MONEY AND YOUR HEALTH. read more

Decent AYCE sushi deal in South OC, can be a wait up to 45 minutes during weekend, since they offer such a great price here for the amount of food that you get.

I was excited to try this restaurant, but the service completely changed my mind. We declined to sit outside because we didn't want to spend our meal getting bitten by mosquitoes. Instead of simply telling us how long the wait for an indoor table would be, the host became visibly irritated. When we asked how long the wait might be, he only kept saying, "The inside is new table." I politely asked what he meant because it wasn't clear, but instead of explaining, he became even more frustrated and angrily told us to go wait outside. We would have been happy to wait for an indoor table if we had been treated with basic courtesy and given a clear estimate. Unfortunately, the host's attitude made us feel unwelcome, so we decided to leave. Customer service should never make guests feel like they're being punished for a reasonable seating preference. I hope management addresses how guests are spoken to, because first impressions matter. read more

Came here with an arcade friend on a Saturday afternoon two weeks back and it was one of those AYCE sushi spots that had been on my bucket list for a while now. Like any other AYCE spot, once you've had one variation done by one chain, whether a regional chain, national chain, or indie mom-and-pop shop, you kind of have a pretty good idea of what to expect and this place wasn't that different than Aikan or Aburi, in that regard, insofar as the quality of sushi goes. The only real difference is that this space stays open late--up to 2am most weekends whereas the former two close rather early like at 10pm. This location in Buena Park has their own dedicated free parking lot out in the front with around 5 cars max with a disability parking spot for a total of 6 but they have a larger lot behind the gate that can fit maybe 20 more cars. Due to where the business is located, even if both lots are filled, you can still park at the adjacent plaza which have much more free parking spots for to choose from, if you don't mind the walk. Once inside, the space itself is shaped like an 'L' and there are many 6 tables and chairs immediately in front of you from the entrance plus another 3 tables and chairs to the right from the entrance plus some front of bar seats, possibly 5 on each side of the L-shaped space. Then there's a covered outdoor seating area with even more tables and chairs there as well. They could probably fit about 46 people inside with another 20 outside. Since my friend and I arrived right at as they opened, we got our choice of where to sit, which was inside to the right from the entrance. Tables and chairs were pretty basic wooden tables and chairs. No cushion but they were comfortable enough. Ambiance. It can get loud pretty fast but is otherwise a quaint space. No TV's or music in the background to my knowledge. Service. The lady server seemed nice enough. They take credit cards with no card minimums but there is a POS fee that you have to pay. Seems like a fixed amount of $3.00 for two AYCE dinner options even though we came around lunch time. Menu wasn't the most intuitive as there were some items that are on there but weren't listed as available items to choose from for the ordering sheet. So basically, you get 3 rounds to order on the ordering sheet and any leftovers are charged as additional, which sucks but understandable. I forgot what the penalty was but it's hefty so do be careful with what you order and how much you think you can eat. Most of the AYCE options were just variations of a California roll or tuna roll but with toppings and different sauces so there's really no point in naming which one's that we ate. My buddy ordered the premium stuff that only gave one per order and you can only have one per round. He says those were all fresh and good for what they were. For the most part, every sushi roll we ordered tasted as it should. Nothing out of the ordinary. Tasted fine but nothing really stood out. For $38.99 per person and with the POS fee and sales tax, it's a bit steep. For that same price point, I kind of feel like a regular buffet would be better bang for one's buck these days, post tariffs and post inflation. All in all, I think the overall experience was acceptable but nothing to really write home about. The only real plus that I can see here is the fact that they open late for those that have been doing their day drinking earlier in the afternoon but otherwise, my personal preference would be leaning towards Aikan or Aburi more, when it comes to AYCE sushi. read more

Worst experience tonight! Went at 10pm for AYCE and by 12:22am we were barely and still on our second round,missing items, etc and the waiter's excuse was "sorry we only have two. Cooks in the kitchen" wtf, how is that my problem!!! ALL the online orders were going out as they were coming in except, we saw a few people come back and complain their order was wrong. We didn't even get our third round of food... which we usually pace and don't get all full from the first two, but by the time we were still waiting for number two, we were so annoyed, my husband just paid and we left. This place is supposed to be opened til 2am and they can't keep up, so disappointed. We also received three dishes we didn't ordered. Only went here because the Norwalk location closed at 11p but I now I know not to waste my time. read more

We put the hurt on 3 rounds of AYCE sushi last night. I think I could have eaten more. Everything was so good! Service was wonderful. I love the new renovations. I will say it's better to eat here than have anything delivered. I have had a few bad experiences with delivery or take out orders being fresh or having acceptable food quality. I only live a few minutes away too. read more

All of it is terrible, The food is awful disgusting not fresh and warm, ordered salmon it was warm, the miso soup was disappointing, all of it was terrible, all the reviews and TikTok videos are fake. 37$ for some crappy food. Never ever coming here again. New management to a cheaper crappier owner. The service was also below average none of the servers told us what anything was, did not help us when we asked, overall terrible service. Also the dishes were dirty, cups and plates smelled funky and drinks from the fountain were off tasting. I don't usually write reviews but this was terrible. The ambience of the restaurant is alright very small. The place is visibly dirty and has a rushed unpleasant vibe. I will also put my review on google because I'm extremely unhappy. They also missed multiple ordered rolls from all you can eat. Asked multiple times and never came. This is honestly the worst all you can eat sushi i've ever been to. Never ever coming back it is awful. Please dont come here its so terrible. read more

the ordering process is a bit confusing, but what a nice and cozy place! this was the only ayce sushi place near our stay that was open late. the vibe is nice and the fish was great quality. their carpaccio was so good! the quality and presentation was definitely up there considering the volume of food they're putting out to their customers. everything was great but wasn't a huge fan of the super white tuna/escolar, it had a really weird fishy taste that tells me it wasn't fresh or it wasn't prepared properly. nonetheless it's a great choice for a late night bite! read more

A little over price for what you get. But I've had worse and been charged more. The service was great . Very friendly

do i really want to expose this location? .... not really, but nonetheless here we are. We were referred to this location by x-fish because they were closing early, and thankfully because we found our new spot. if you blink, you'll miss the turn. They are located off the main road, and have ample parking in the back. The restaurant is intimate with plenty of seating. Service is attentive and rounds come in a timely manner. Fish is always fresh and quality flavors. read more

If you're looking for sushi past midnight, this spot definitely fills the gap -- they're open until 2am, which is a lifesaver after a late night out, an after-party, or even a long day at Disneyland. That's really their strongest selling point. The service is friendly and welcoming, which makes the experience better, but the sushi itself just isn't the freshest. I've had much better quality at most other sushi places I've been to. The fish and rolls are edible and will satisfy a craving if you're starving, but don't come expecting top-tier quality. Overall, it's worth it if you're not picky and just want sushi after hours when nothing else is open. For late-night eats, it does the job -- but for a quality sushi experience, there are definitely better options during the day. read more

Update to my review 6 years ago! Whoa! What happened to this place? It used to be really good here back in the days. After dinner last night, I was disappointed. Sushi here was not fresh at all. Very fishy taste, either it was spoiled or just poor quality. Pieces were really skimpy. Rice falls off immediately. Most reviews might be blind sided because they open late, ayce, etc. Ehh it's pass. read more

We love this place so much. My husband and I are regulars in this location. They have the most hospitable servers who welcomes you with a smile and top notch customer service! Above and beyond is a way to say it. Love the ambiance it's pretty chill and comfy. Food is phenomenal! It's so good amd super fresh sushi! Love it! read more

Servers were friendly, took care of us, didn't really need anything. Small interior, cozy, relatively casual. Seared salmon was the best, had some soy something along with the dot of hot sauce made it my favorite. I'm not a sushi guy but a friend was feeling sushi. Salmon collar you're only allowed one. Quality was OK, not great, not bad. Shrimp skewer is a pass although there is a healthy amount of shrimp in there. Mushroom skewer was interesting. Friend really liked their water which is funny since he said he is sensitive to both water and ice, seems like it's very clean LOL Uh, overall it's not the best spot as It was hyped out by some people I think for AYCE sushi. Personally, for the price, I'd rather eat Thirsty Cow but I did thoroughly enjoy the seared salmon pieces and it's a nice place with it's own parking lot which seems to have no issue with space (Monday night though). Can be a little dark further away from the building but it's an enclosed lot so shouldn't be any issue there really. read more

OVERALL : AYCE sushi in OC open until 2am!! OC has plenty of AYCE sushi spots, but I was glad that I discovered Ozen bc they are open late and great for a late night out with friends or a casual sushi date! It's a low-key spot, but they have a lot of items on their menu which you can get a-la-carte or AYCE. They had both indoor and outdoor seating and service was quick on a late night when we came around 9pm. PARKING : They have a parking lot behind the restaurant! FOOD/DRINKS : You'll find all your classic rolls here, as well as nigiri, handrolls, baked rolls, carpaccio, tempura, sashimi, udon, and ramen. They also had plenty of alcohol to go with the meal - we got a nigori cloudy sake (strawberry) and it was great! Tasted like juice after a while LOL The portions / ratios were perf for AYCE -- not too big so that I could try a bunch of different things. My favs were the spicy tuna crispy rice, carpaccio, seared salmon, scallop, spicy tuna, and the hamachi collar. The fish quality/selection is of course, as expected, not going to be like a fancy upscale omakase meal, but that is to be expected at a casual AYCE spot. For an AYCE spot, the fish is fresh and tasted clean! Would def come back again next time for a late night meal. read more
