I stopped by Koyi Sushi for Lent Friday and was seriously impressed. It was the perfect spot for a no-meat day their all-you-can-eat menu has such a great variety, and everything tasted fresh and flavorful. For the price, you really can't beat the value. The service was also on point attentive, friendly, and quick without feeling rushed. What I really liked is how lowkey and relaxed the spot feels. It's not overly crowded or flashy, just a solid hidden gem in Montclair where you can enjoy great sushi. Definitely planning on coming back again soon! read more

Food was good for an AYCE sushi restaurant, but there's a lot of room for improvement. First of all, it was hot in there. Like REALLY HOT. On a 100+ degree day the door was open. I noticed they had AC splits instead of central air, and it just felt muggy in there. Definitely not the proper environment to serve RAW fish in. The service was prompt, but not the friendliest. My husband and I were the only diners in there, and it seemed like they were watching and waiting for us to finish so they could close up. At some point during my meal a Maybelline Dream Matte Mouse sticker fell in my lap from under the table. Just not the best dining experience overall. read more

Certified this place is a little gem in the cuts of Montclair. It's on of the few sushi AYC and I highly recommend. We ordered 7 different rolls and we are happy with all of them. The customer service was quick and great. Support local. read more

Always such good service and the fish is so fresh everytime! The no rice rolls are some of the best I've had and their fish to rice ratio for sashimi is divine. read more

Koyi Sushi - Sashimi - Sushi Bars Near Me - Montclair, California

came in on a Tuesday around 7pm for AYCE sushi dinner. restaurant was empty. got seated quickly and explained the menu items. we picked the premium $48.95pp so we can try the sashimi plate. we also ordered sushi, rolls, appetizers. one chef, an asian, but not sure if he's japanese. the kitchen food and the sushi food came in good timings. all the fish tasted fresh for an AYCE restaurant. fish slices are good portion with good rice portion that's not too big to fill you up. baked green mussel was a little burned. chicken wings were juicy. beef teriyaki was a little dry. calamari tempura was chewy, not impressed. if I'm in the neighborhood I may stop by to try the premium menu again. read more

As a couple that's very used to sticking to one sushi place and finding nitpicks in any new ones, this restaurant blew us away. First off, the quality of the sushi is amazing for the price. And second, the price is incredible for the quality. For an AYCE sushi spot the quality of the nigiri is delicious with just the right ratio of rice to fish. The appetizers were also tasty and came out quickly. The staff is also so kind and helpful and attentive. Whenever we needed anything they were already bringing it to us or immediately around. We will definitely be coming back again and again. read more

Decided to try out Koyi cause I pass by it all the time and I'm always down to try new things. As far as the all you can eat experience, I would say it was pretty average. You get 3 rounds and you can select different tiers of AYCE. The service was very quick (but then again it wasn't super packed) and my waitress was doing an amazing job. She was the only one working the floor and she did awesome making sure everyone was being attended to. Koyi is a small space so it doesn't seat very much. If you're coming with a large party, I might try to call in advance to gauge out the environment. Now as far as the food is concerned, it met my expectations and while it didn't blow my mind, it hit the spot. What I really appreciated was that their meat to rice ratio which made the price worth it. Overall, I'd recommend Koyi if you're looking for a quick bite. read more

I am always hunting for new sushi places to try, so when I heard sushi VIP was under new ownership with a new name of Koyi Sushi, I was very excited to try it! The sushi was delicious! The fish tasted very fresh and the fish to rice ratio was very good! I loved that they had specialty options like the blue fin tuna and giant scallops to try! We tried two of the no rice rolls which were both good but had a bit too much sauce for my liking. The same went for the fried avocado bites. Delicious, but a touch too saucy- but I have no doubt that if you requested less sauce that they would be happy to oblige. The service was good and the waiters were very polite. One thing to note is if you have sensitive ears like me, don't sit below one of the TVs since it can get a bit loud. The actual vibe of the restaurant was okay. Some of the lightbulbs were mismatched (white light vs warm light) and not much in terms of atmosphere. I also liked the fact that their menus had pictures of the rolls, but the pictures are so small they are very difficult to see. The menu itself did have quite a bit of variety. One thing to note is that you order the individual pieces, not the typical sets when it comes to nigiri. (If you order 1 salmon nigiri, you will get 1 individual nigiri). I liked this because it lets you order odd number. They do not allow half orders for the AYCE. Overall I really enjoyed Koyi Sushi much more than I did under its previous owners! The sushi was excellent and I look forward to going back soon. Date of visit: 06/01/25 read more

Fantastic sushi spot and our new favorite! We've been getting tired of the high bill and low quality sushi we'd been getting at sushi Martini, so we're very happy to have found this spot. Sushi is of a good quality, with excellent rice - fish ratios. They have a wide selection on the menu, and the non-rice rolls are a nice inclusion. Only complaint is the heavy use of sauce, but I'm sure the chefs will be happy to adjust at your request. The chefs at the bar are very welcoming, and you can feel their appreciation/passion for their restaurant! Staff/servers less so, but +1 to the chefs. Ambiance is a bit odd, you can definitely feel like the place is still getting its vibe settled, lighting needs work, but I'm excited to see this place grow. read more

This place is really new and I love trying out new places! The girl working the front, I didn't get her name was really nice and really on point with checking on us. She explained the menu to us and kept checking back to make sure we had everything we needed. The dishes came out quick and the kitchen items were really hot and fresh. The fish to rice ratio is so good here. The rice is so small and I love when places do that because they aren't trying to fill you up with rice. Its in a decent sized plaza with tons of parking but it can get packed due to all the establishments open. I'm always looking for new AYCE places so I'm glad I found this spot. read more

Good place to try for ayce sushi! Lunch was $29.95, was a bit adamant based on reviews but after trying it for myself it was a nice time. Nigiri was good, the roll selections were nice - mango salmon was our favorite. They had some no rice rolls & appetizer options as well. Waiter checked up on us and refilled our water, place was nice and spacious. They do close at 3:30 and reopen 5 PM on the weekdays so make a note to come before 3 for ayce. Overall would come again :) read more

Miso soup was lukewarm and had no tofu or seaweed Baked mussels were bland in flavor Sunomuno Cucumber salad wasn't good--Cucumbers were opaque and the sweet vinegar taste was overwhelming Spicy scallop handroll was definitely spicy, but in a good way Tuna sushi was mild in flavor Octopus sushi was clean in flavor and big pieces Squid sushi was also clean flavor and not overly chewy Salmon was very lean, but good Sweet shrimp sushi was chewy and underwhelming Imitation crab did not have enough mayo Mackerel was overcooked Yellowtail sushi was the best we got--flavorful and tender Rice was a bit dry Food overall rating: 5.3 Customer service good Service fast Atmosphere nice - calming music Cleanliness very subpar 5.6 overall scoring read more

I'm a little hesitant when it comes to AYCE anything because I feel like majority of the times, the quality is mid. Came here for a late lunch because I saw that it was new. There was only 2 parties inside when I got there, its pretty dark inside. Pretty plain interior, quite a few tables & sushi chef is off to the side. Our server was really nice and attentive to all parties as she was the only one on the floor. The food was okay, not bad but certainly not the best either. Would I come back? Probably not, nothing stood out to me but I'm glad I tried it out. read more

We visited Koi Sushi today. Upon arrival, we observed that the establishment was in its soft opening phase, and order fulfillment ceased at 8:30 PM. It is in the old sushi v. I. P building. We received notification that the grand opening is planned in one month and Operating hours will extend until 11:30 PM. We ordered a few items from the appetizer menu and if you rolls for our first round We received encouragement to increase our order due to the kitchen's impending closure within the hour. However, their all-you-can-eat policy stipulates a $2 per piece charge for any leftover sushi. Therefore, we exercised restraint in our order volume. We sampled their sashimi, traditional sushi, tempura, and baked selections. All items were freshly prepared and served promptly. We also found their hot tea to be quite palatable. Our server demonstrated extensive menu knowledge and maintained a professional and courteous demeanor. With our table and the ones around us. I would appreciate it if more servers provided the same level of service as she did. Ample parking is available despite the shopping center's high traffic volume. The new ownership appears to have implemented positive changes. A highly recommended establishment. read more

I tried many AYCE place and this one really surprised me. The place is tiny with less than 10 tables only one waiter. I am not complaining but this is normal for lunch. The surprise is the small portion of rice and the sashimi is pretty thick and good quality compared with other AYCE. Each nigiri comes only 1 pcs so I can try as many things as I want, this is amazing for small group. Also you need to try the tempora very light not oily and brown yellow . Not many AYCE I want to try twice, this is the one. Hope they can keep the quality. read more

Eyes bigger than stomach? Welcome to Round One at Koyi. Took the fam for the all-you-can-eat sushi marathon--and holy wasabi, we got wiped out in the first round. Everything was that good. Crispy tempura, sashimi so fresh it practically swims off the plate, and specialty rolls that looked like sushi art gallery pieces. Service was lightning-quick and staff kept the vibes high, so by the end we were full, happy, and already planning our rematch. Fair warning: come hungry, but maybe pace yourself--Koyi plays for keeps. read more

Koyi Sushi - Sushi - Sushi Bars Near Me - Montclair, California

They should have a disclaimer about their menus. We went with a party of 20. Called ahead. Made a reservation. That phone call should have been when to relay what we were told once about to order. Half our party wanted ayce. The other, off the regular menu. They don't have combos or anything. It's either a la cart(currently 50% off or ayce. That's fine. Everyone was looking at their menus. Then the waitress comes in and says the whole party has to do one or the other. They were worried about sharing. We thought we heard wrong. The other waitress comes in and says the same. Then the manager came in and said the same. We were frustrated to say the that cause we all drove 30-45 minutes to go there. We almost got up and left. Eventually we were able to talk them into our party splitting. One side was ayce, the other a la cart. Fine we were ok with that. The two waitress had heavy accents so it was a little hard understanding them. But they were very nice and friendly. Got us what we asked for. Delivered with a smile. The good was ok. Their rolls were all pretty basic. Morning Nancy it intricate. Some fried rolls. Some fresh. Nigiri. Rice was small compared to the fish. Appetizers. Everything was fresh. The chicken wings were delicious. If I'd have put some sweet and sour on them? Mmm. We quickly forgot about the issue upon arrival and started enjoying our food. We were done eating. Asked for the check and the said wait, we have a cake for you. We told them when we made the reservation it was for a birthday. They brought out a tiramisu cake from proud that said happy birthday idk if they already had it or if they ordered it special. Regardless it was awesome of them. All in all, we enjoyed our time. read more

My bf and I went in for AYCE lunch buffet. Sushi was fresh and DELICIOUS! We enjoyed everthing we tried and ordered. The service was fast, our food was out quick, it was a low key Sunday afternoon. Can't wait to come back! Next time I'll post which ones were our faves. read more

Great food. I started with the seaweed salad, which was a small enough portion to not be overwhelmed. Then I had a spicy tuna hand roll, which had the perfect amount of seasoning on it and not too much rice. We then had some nigiri, including the salmon flush. Very good portions of fish compared to the amount of rice. Iris was our server. She was very attentive to our needs and extremely polite. She poured all of our drinks as is customery. I would definitely return again just for Iris and her service. Thank you for the great meal Koyi Sushi. read more

We're big fans of AYCE sushi--especially my husband, who can definitely eat his share--and were excited to try out Koyi Sushi's new location in Montclair. We've heard great things about their OC spot, so we stopped by on opening day after seeing their soft opening announcement on social media. It was a little confusing at first. There was no working phone number, and even when we called the OC location, the staff there didn't know if Montclair was officially open. We decided to take a chance and went anyway. The storefront still had the old restaurant's sign and number, but once inside, we confirmed it was under new ownership. The sushi was fresh and good for the price--though unfortunately, they were out of jumbo scallops that day. Kitchen items were just okay; a bit oily and overcooked for our taste. The biggest downside was the cleanliness. The floor looked stained and dirty, and the tables felt greasy. The whole space could really use a deep clean, especially for a brand-new opening. Overall, it was an okay AYCE sushi experience. My husband had no issues, but I ended up with a stomachache and diarrhea later that night--not sure if it was related, but worth mentioning. Hoping they iron out the kinks soon, because there's potential here. read more

For a place that had no customers, the wait staff was very slow to service me. I went in alone on a Monday afternoon, 2:30pm. On the menu I pointed out that I wanted to come in for that happy hour price listed at $24.99. The lady tells me that the price has changed and now it's $29.99. Not sure why their menus haven't been updated, but that threw me off. Once I sat down, I took a look at their small menu. And was ready to order after 5-10 minutes of being sat down. Again, nobody else in the restaurant except me. The man at the sushi bar look at me and said hi and that's when the waitress came to ask me whether I was doing AYCE or not. As I informed her that I was doing AYCE even at their falsely advertised price, she let me know that all I had to do was mark down items on the menu, as if she had given me a pen to do so already. At this point, the wait time, the misled information, and the misinformed way to order all threw me away to not want to dine in. If you wish to come here, please know that their AYCE is $29.99 and might be a wait to be served even if there isn't anyone else in the restaurant. The food? I can't tell you whether or not if it's good. If the service isn't good, I'm more than happy to dine somewhere else. read more

Horrible. Don't waste your time or money at this place. The food is totally lacking. The simple things like edamame was dry and looked old. The rolls were discolored and tasted like they been sitting out for days. Flavor was horrible. The only positive about this place is that it's all you can eat, but beware because it's less than mediocre food. You definitely need a beer to chase down the food. The restaurant was almost empty at 6pm on a Friday, that should've been the sign to walk right out. Another sign I missed was the letter grade B on the outside window. Yelp reviews let me down. Never coming back. PERIOD read more

Came at lunch on Wednesday July 2nd The sushi was alright, but I was pretty disappointed to find fish bones in my rolls and nigiri. It was not just once, but four (4) times. It happened with both the salmon and the yellowtail. Kinda takes away from the experience when you're constantly worried about biting into a bone. The place itself is nice and the service was decent, but for a sushi spot, I expected better quality control. Not sure if I'll be back. read more

Good sushi nigiri small rice portion. Many choices for appetizers. But service need improve to slow
