Nice little place offering sushi, ramen and other Japanese specialties. Service was attentive and delightful, spicy miso ramen was excellent, although not the best I've ever had. I did not have sushi or sashimi, only a special roll and, like the ramen, it was very good, but not over-the-top memorable. I've been to three sushi restaurants in Montclair, and so far, Koshi is the best. read more

Came here for takeout twice, i love their special rolls and sets they put on their menu. Most sushi places have some variation of it, but I feel like there are some choices that I don't really see often that really call to me! The quality is pretty good- we usually end up coming at the latest hour for as a late minute decision for take out, but I'd love to come and sit inside one day when we have time :) Theres a lot of street parking nearby and its close to the train station. One of the biggest stand outs is how friendly their staff is. Even though I'm only inside briefly for takeout, I always leave a little cheered up. (Excuse the poor presentation in the photos- definitely due to our negligence carrying out food home haha...) read more

Sushi Koshi - Lunch special sushi and California roll - Japanese Near Me - Montclair, New Jersey

There is absolutely a reason Sushi Koshi has hundreds of reviews and almost perfect 5 stars.... They are the best. Their sushi is incredible- fresh and flavorful. And their staff is amazingly friendly. I have been a customer for years and they are still my favorite spot in town. I love sitting outside on a nice day. It's a quiet wonderful place to sit and enjoy sushi. They get busy sometimes during peak dinner hours or even lunch. They work hard to take care of orders in a timely manner. read more

Our favorite local sushi spot. Always great service and great food. Extremely consistent and fresh. The miso soup is a favorite to start the meal and the shrimp tempura and dragon roll are fantastic. read more

Great atmosphere and amazing staff. Joon and Cherry are super friendly, courteous and attentive. I enjoy eating at the restaurant as it has a good vibe to it and I also do take out. I stick to the standards of tuna and salmon rolls and their fish row is good too. And the prices are good. Teriyaki dinner box is also good. Good. read more

I'm not going to dive into it the way I usually do, I'm just going to say eat here. If you want sushi, go here. The menu, the quality fish, the kindness of the workers - it doesn't get better than Sushi Koshi. read more

I need to come to this place more often. Always great and friendly service, high quality food, and so reasonably priced for Montclair. I started with a house salad with a very generous portion of ginger dressing - it's so nice to have dressing served in a small non-plastic single use container - I'm hoping more restaurants will return to doing so. The naruto rice-free roll (combo of 4 fish, crab and avocado) wrapped in cucumber with sunomono sauce is great for anyone limiting carbs but also a very refreshing and light combination. I ended with as usual great and and authentic bibimbap, requesting a raw versus fried egg, and they were very accommodating. The hot green tea dispensed direct from a press at the table is a nice touch. read more

I got delivery from Koshi earlier this week and it was really great. It will be my new go to sushi spot. All the roles we ordered were delicious and they even threw in some miso soup for us. I ordered directly from the restaurant by calling in--I don't know if it keeps the delivery services from getting a cut, but I want to support local businesses as much as possible. read more

BEST SUSHI IN TOWN!!! Found out about this place from my daughter. She started ordering from here. Please note I am not a sushi fan, but this sushi is delicious and fresh. I order the mango tango and a couple of other rolls. It always hits!!!! read more

Tried Sushi Koshi for the first time after living in the area for nearly two years. It's a really small restaurant in the strip of Watchung Plaza - there's a little sushi counter area and then a small room attached with a handful of tables. We came pretty close to closing and they sat us anyway and were really nice. We ordered a few pieces, miso soup, and some sushi rolls. We loved that the sushi pieces came with some tiny toppings and a little seasoning on it - so good. We ordered some normal rolls and some special rolls and the special rolls which are usually too much and too heavy on the sauce for me were delicious and light and so yummy. The sushi rice was definitely fresh and room temperature even though it was the end of the night. We will definitely be back!! read more

O M G. The sushi here is incredible. When you order, they start you off with a complimentary app that's delicious. Next onto your sushi. They have tons of specials on the board, special rolls, and your standards. I get mine with black rice and it's delicious. Aside from the food being great and the fish being fresh, the staff here is so personable and welcoming. I am very impressed that they remembered me & my boyfriend after just one stop in here, and I will continue to come here! read more

I love the mixed rice! I have no idea what it's made of but it's great. I did not like the special crunchy roll. Way too much crunchy stuff on top. read more

Yum! Just Yummy food here and great service! My friend raves about this place and she was not lying. We decided to have a late dinner here on Thursday night and were greeted with a warm smile. The waitress brought us a salad, a taco sushi and a piece of a sushi roll on the house. The taco and sushi were delicious. Next time I will definitely try one. Now lets talk about the star, the spicy ramen. It came in a huge bowl and it was delicious. So big I had to take some home and let me tell you it tasted even better the next day. Not over whelming spicy. Just perfect. I will be back soon as I have not been able to stop thinking of this amazing place since! read more

Found this place on an online forum and decided to give it a try. This place is legit. Their ramen (not on the menu but is posted on a chalkboard outside if they have it) is $12 and suuuuuuper good. First of all, the taste is amazing (I got the spicy miso) and it comes in a huge bowl. Aaaaand you don't have to pay extra for the egg like other places! read more

This is my favorite restaurant in all of the tri-state area. Last December a friend took me here and I've been here at least six times since then... each time it gets better and better. The owner, Jay, is a brilliant sushi chef and the customer service, Ellie, is so warm and friendly! It always feels like home. Now for the FOOD. The lunch specials are so worth it but I really come here for the amazingly fresh and delicious sushi. I ALWAYS get the T.G.I.F roll- Jay knows exactly how to sear crab and salmon- and the seared sushi appetizer is so perfectly cooked. I 100% recommend the mixed rice instead of just white rice. It gives the sushi another element of flavor and it's healthier to boot! My other favorites are the special avocado bake appetizer with seared crab (omg it's so good), the OMG roll, and my boyfriend loves the tempura rolls and anything else seared. The Bulgogi was flavorful but not too sauces, even the vegetables were edible and fantastic. Get mango mochi for dessert!!!! I recommend it this place whole heartedly. read more

Small place with friendly staff. The staff gave us free dessert at the end! Overall sushi was pretty good. There were 1-2 special rolls that I wasn't a fan of but might be personal preference. Their salmon sashimi was really fatty and melted in your mouth. read more

The service and sushi deal is great here! It's a nice intimate location with street parking nearby. I never see the option to have purple rice, so that was a nice surprise! The "Roll for Two" deal is perfect with 5 total rolls- California, Spicy Tuna, Eel, Shrimp Tempura AND a special roll (which already costs about half of that) for $29.99. We ordered an extra special roll, and that was the perfect amount for two people. The meal came with Miso soup, complimentary sushi piece, and mochi for dessert. I did notice that all the special rolls were mostly some variation of spicy tuna or fried shrimp in the middle rather than any other option. Regardless, it is definitely worth going! read more

Horrible experience with takeout tonight. I ordered beef teriyaki and they gave me beef bulgogi. I called them to complain and they argued that I was wrong and that this was the beef teriyaki. You call yourself a Japanese restaurant and this you are saying beef teriyaki is. Nonsense. I will not be ordering anything from them again. read more

Very good. Staff are friendly, nice atmosphere. Lots of vegetarian options, with some unusual ones. Best we have found in the area.

I was in here yesterday and I just feel like I need to put in my input. While the food was amazing the service was less then adequate. After receiving are order we realized there was miscommunication in one of the dishes which is totally fine but when we addressed it the server became passive aggressive. While we were polite the whole time it felt like our server was becoming annoyed with us. At one point we heard her say in annoyed tone "these girls". While I wouldn't say not to go to this restaurant I would just watch out for what server you get. read more

I'm not sure which was worse; the service or the sushi. Special rolls were all so similar: 5 out of 15 rolls started with "fried shrimp". Smothered in sauce. Little to no taste. Reading the other reviews, you all need to get out more and find GOOD sushi! read more

My brother and his wife introduced me to Sushi Koshi 2 years ago and we all agree that it's (still) the best sushi in Montclair. I do wish they had more special rolls without fried shrimp, but the combinations are so tasty regardless and the sushi always tastes fresh. The people who run the place are sweet and often give out free rolls. The only downside is that you might wait a while if you do takeout -- but that definitely hasn't stopped me from coming back. read more
