We normally do takeout, which is both amazing and quality and quantity as well as service! It's no wonder this neighborhood staple is so popular and busy all the time! They know what they're doing in terms of having the freshest sushi and sashimi around. We like sitting outdoors and great weather so it's great that they have outdoor tables. On a recent weekday, I met my folks who regularly dine in, for lunch and sat in the back room, which is quieter, and we had a number of specials from their lunch menu, which has great options at very affordable prices. I've orders the Sushi platter for two as takeaway for parties and it's always a hit in quality as well as amount to share. Highly recommended! read more

Loved Sushi Koshi! Fish was fresh and portion and quality justify the price. Space was limited, but cozy, and staff went above and beyond to be welcoming. We came closer to closing time, but staff didn't rush us. Watching roll & Soho roll was our favs. For sure coming back! read more

This restaurant was such a wonderful find! My friend and I walked in on a Saturday afternoon, and we were immediately seated. The interior was so pretty and made for such a calm, peaceful environment. I ordered the chirashi bowl from the lunch special menu, which was delicious. The sashimi tasted so fresh, and the presentation was great, too. My friend ordered the shrimp avocado roll and salmon roll, which she enjoyed! I would definitely come here again to try more. read more

Two weeks ago my colleague and I went here and said we only have 10 minutes. Can you please get us three sushi rolls or Teachers and we have to get back at work they were so accommodating and the sushi was so fresh. Thank you. read more

Continuing on my local sushi tour we find Sushi Koshi. It was delivery this time, but will stop in to check out their sit-down next time. To start we ordered Gyoza (3/5), these were cold for some reason while the complimentary miso soup was warm/hot. The pork filling was good enough. The Tuna Tataki (5/5) and Shashimi (4/5) were both very good and fresh as can be. For our sushi rolls we got the JJ Roll (5/5) and the Blooming Roll (4/5). Both were excellent, but the JJ Roll was our favorite. The Crab, fried shrimp, cream cheese, etc... were the perfect match of flavors for so much going on. The Blooming had ample amount of tuna, white fish, and tuna on top--something was missing though. They threw in a a free roll which I thought was great for a first experience with them. They never mentioned what the roll was, but it was great. This place was consistent compared to our last sushi experience in the area. Will try again. read more

Great little sushi restaurant in Montclair. However on a Thursday night the sashimi was tasteless. My husband loved the special rolls but that because they were covered in sauces in addition to the tons of wasabi, Ginger and soy sauce he adds. read more

Came here for a weekday dinner and was seated right away. It's definitely a small restaurant, looks like seats about 20-25 people indoors, but they do have a few tables outdoors as well. I love a sushi menu with photos, since it's hard to imagine and it's just easier when you can see it visually and see how the ingredients are done for the rolls. Sushi tasted fresh, though food took longer than expected around 15-20 minutes. Price was fair and expected for the area. Staff was friendly and food was good! The only real downside was that there were flies flying around every few minutes so that was a bit annoying, so maybe would opt to come here again and try sitting outside to avoid this issue. read more

Came here for takeout sushi and the staff could not be nicer! The sushi was SO fresh and delicious and I definitely recommend!!

Been here a few times because we really enjoy the sushi here and tranquil decor! The times we've gone we also have never had to wait too long for a table even though it always seems pretty busy. I did recently order the yakisoba just to try it and it was good but feel like it could have been saucier. Planning to come back and try some of their other dishes as well but the sushi is for sure delicious! read more

Such a great spot. I remember looking for a Japanese restaurant to go with my kids as a family. We found this one and we have never looked or been to another spot. They absolutely love it. The place is fairly small but it does have seating , I guess maybe reserve if you have a party of 6 or more. The kids and I love the food. The staff is always so friendly and attentive. It's really nice family spot or a date night spot. The food is always fresh and delicious! Highly recommend! read more

Solid 4.5 stars! We wanted to see for ourselves after reading the great reviews and Sushi Koshi did not disappoint. We were lucky to get a reservation. The restaurant is buzzing, small and charming. Our table started with the Avocado fries and gyoza. Very good. And we ordered a bunch of special rolls: tuna and salmon dragon, volcano, sushi koshi, lava and Grand Canyon rolls. All delicious and fresh. Great plating and presentation. Definitely worth checking out. read more

Came here for lunch. The sushi lunch special had really fresh fish and rolls. I'm not usually a fan of California Rolls, but these had a punch flavor in a good way. The salad and miso soup that came with it were also good, but nothing notable. I also sampled some of the chicken teriyaki lunch bento. You get a lot of food with it, including edamame, miso soup, salad, gyoza, and the teriyaki. The gyoza were really crisp and tasted freshly made, and the teriyaki was perfectly cooked--better than what I've had in Seattle where it's really popular. I also noticed that they also have stuff like beef bulgogi in a stone bowl, poke bowls, and chicken katsu. I'm going to have to try those next time. read more

I've been here three times and have even met up with friends for dinner. The sushi preparation never disappoints -- always fresh and delicious! Definitely worth the one-hour drive from Sparta, New Jersey. read more

Service was 4/5. Nothing spectacular but nothing terrible. Ambiance was 4/5. Again, nothing spectacular, nothing terrible. Food. We got a Kani Salad to split; it was oddly watery and while we know it's imitation crab meat, it had zero flavor. For dinner, neither of us were in a sushi/sashimi/roll, so I got a shrimp teriyaki dinner box and my GF got a chicken teriyaki dinner box. While filling, the shrimp pieces were quite small and well over-cooked; they were dry and chewy. The chicken was also a little on the over-done side. Neither came with rice, even though the menu says, "served with rice, soup & salad" (the soup was pretty good). When we asked where our rice was (because our server asked us at the start if we wanted white or brown rice), we were told it was for the rice in the included-with-the-dinner-box California roll. Would definitely NOT re-order a teriyaki box. 2/5. 4/5 + 4/5 + 2/5 = 10/15, thus the 3-star rating. Perhaps we shall give this place another try when we are in the mood for sushi/sashimi/rolls, but I'd recommend not getting a teriyaki box (but YMMV). read more

So friendly! My husband and I loved being greeted with several smiling faces as soon as we walked in. The space was cozy with simple Japanese decor. We came for lunch and shared the beef goyza for an appetizer, which we both really enjoyed. I had the chicken lunch box with the avocado cucumber roll. I was so surprised by how much food it was! It all tasted delicious and I loved the variety of items it came with (soup, salad, chicken, goyza, and edemame). My husband had the chicken katsu and lunch roll. He loved every bite. We were stuffed and definitely had leftovers. Can't wait to come back! read more

Wonderful selection of rolls - really good fresh fish and great friendly service! We sat outside so I can't speak for what the inside was like but definitely plan on coming back to try it. read more

Ordered sushi for delivery. The tuna sashimi was kind of watery and had no flavor. The yellowtail tasted off and it was all generally bad.

Ordered pick up with coworkers for lunch and can't wait to have more of their lunch specials! We all got the Two Rolls lunch special which includes a salad and miso soup. Including tax and tip, we paid ~$17 per person - a very good deal for a delicious & filling meal! The online ordering platform is very easy to use - but note that the menu is available around 11am but you can only checkout at 11:30am. read more

I'm giving sushi Koshi 3 stars because there were fruit flies everywhere! It was actually pretty gross. Sushi was good. We had gotten 4 rolls I loved 2 of them 2 were not my favorite but the others in my party did enjoy them. Servers were nice. I would have give 4 stars if it weren't for the flies. We were constantly swatting them away. My brother in law had them in his cup which was very gross. read more

This review is for takeout only but it was packed when we went in to grab our order. Fantastic and reasonable sushi in Montclair. I got the maki combo of spicy tuna, crab, and salmon for $12.99 and a miso soup for $2. Sushi tasted fresh and filling. Hands down, this is the best place we have tried yet! read more

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

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

This spot has a great 3-person deal (they do 2-person as well). You get a variety of basic rolls (eel, spicy salmon, California roll, shrimp tempura) and you get to choose 2 specialty rolls. You also get 3 miso soups- $50! Not bad. We got the Dancing Eel roll which I thought had a good amount of eel. The Salmon Dragon roll was delicious. All of the standard rolls were, well, standard :) When we were finished we received a cut up piece of MOCHI with the bill. Very nice! While I didn't have the 5-star worthy WOW factor at this sushi restaurant, I would definitely return to try more of their specialty rolls! 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

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
