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

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

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

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

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

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

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

Ozen Sushi - Japanese Near Me - Buena Park, California

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

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

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

***Don't eat here!!!*** Horrible service, room temperature paper thin carpaccio that cost $17 for 6 pieces which I only ate 2 pieces. The avocado on the roll was dark, the salmon didn't taste fresh. Ended up getting food poisoning. 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

Called 3 times and got hung up on 3 times while people were in the background laughing. Called a 4th time and finally got someone to say something and just got a " hello" I followed up with asking my question and a point blank " no".

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

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

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. Service is fast once your party got seated. The rice to fish ratio is good. Overall I enjoyed the experiences and the sashimi quality; however, some pieces of tuna was not that fresh. 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

Ozen Sushi - Fees! - Japanese Near Me - Buena Park, California

Took my son here after his senior graduation. It was late in the evening getting closer to 10:30 PM and it was crowded which was no issue. We got seated and placed our orders. Food took a little longer than expected, but the first two items were fine. They tasted good and seemed to be served promptly after they were made. That's when things kind of went downhill. We ordered a super spider roll and after waiting about 20 minutes and noticing that people that had just come in were being served their food I flagged down a waiter to ask what happened to our order. He subsequently advised that he just put the order in and that the kitchen was busy. I didn't get a chance to cancel it as he promptly walked away. We got served the super spider roll, and it was just terrible. The tuna was pasty and like dog food. The crab on top was not good at all. I asked for the bill and alerted the cashier that that role was not acceptable and I did not wish to pay for it. We left it on the table, and it was not eaten, except the in pieces that we had tried to establish that we absolutely did not like it. The cashier indicated she would give us 30% off, which I interpreted as 30% off the bill. I informed her I didn't need 30% off the bill as the other items were fine but that the last role was unacceptable and she indicated that she's a cashier and only a manager could do that. I was confused until I saw the bill and figured out what she implied was. She can only give 30% off the role that we didn't like even though we didn't eat it. This is unacceptable. I don't wanna pay for something that is terrible. I didn't eat it. I told them about it and to imply that you're gonna take five dollars off a roll that is un edible is not good service or good business practice at all. This place has a niche and that they are open very late and are very crowded but the location and the outside atmosphere is questionable there was people just hanging around in the front who didn't look like they were guest of the restaurant and just seemed shady altogether. The parking lot was terrible, but that in itself is a different issue. I feel if the food and service were consistent then it would get a better rating. But it just seemed there is too many disconnects between the various servers and trying to get your food in a timely manner and then ultimately trying to get your bill in a timely manner, simply didn't meet my expectations. read more

the worst service ever. All you can eat they advertise. $40 plus per person. our family of 5 and they add the 18% gratuity for service that they did not supply. I took my family there last night. the waitress was nice at first, then disappeared for an hour. did not come check on us and still wanted us to pay the bill. $250 for bad service, and not taking care of customers. our regular sushi place was closed so we tried this one, do not go here. It is horrible, bad and over priced. This used to be Joe's sushi just so you know how well we know all the good sushi spots. Will never come here again. Super disappointed. We paid our bill and walked away, people pay good money for food service and good food. read more

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

Have you ever struggle finding an AYCE sushi spot for late nights? I know I usually do (sometime I crave sushi at 9pm, and by then most spots are close). Ozen tho is open until way past midnight!

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

This place has pretty good sushi, but what really stood out to me was the service -- it was even better than the food. The staff was attentive, friendly, and made the whole experience enjoyable. They were open late when I first went, which was super convenient. However, when I tried going back a few times, they were closed. I'd recommend they update their hours online to avoid any confusion. Overall, still a solid spot with great service. read more

Sushi is always great. The service is also great and place is very nice and inviting.

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

This little hidden gem offers both AYCE and ala cart. Their menu is large enough to have a few items you enjoy yet small enough you don't get lost. The restaurant is small, cozy and clean. They offer a covered patio for those days you wish to dine outdoors. The service is efficient and friendly. At first I didn't think there was anyone at the restaurant as there were no cars parked out front but it was pretty packed and I found there was plenty of parking out back. They have some yummy apps including one I could eat a boat load of their spicy garlic edamame. I couldn't get enough, thankfully I went with the AYCE We enjoyed their rolls and tried a new to me dish that was spicy tuna crispy rice. It was both delicious and fun to eat. They offer a variety of apps, sushi, hand rolls, baked rolls, tempura rolls, veggie rolls, classic rolls and no rice rolls.
