Sushi
Koshō Restaurant at The Barlow is a modern Japanese and sushi restaurant in Sebastopol with a progressive focus on food, local ingredients, and sustainability. We utilize local purveyors for fresh produce and meats as well as national and international providers for fresh seafood and sushi grade fish. Koshō derives its moniker from the condiment of the same name, Yuzu Koshō. Known for its spicy, acidic and balanced nature, it appears throughout the menu in various forms; including Meyer lemon, grapefruit, and satsuma orange koshō. Our chef, Jake Rand, has traveled to many of the famous markets in Japan and has a vast knowledge of selecting top ingredients and the freshest fish and has over 20 years of experience preparing them.

The portion size is relatively small for the cost but the quality of the food was excellent. Will recommend to friends and will dine there again.

After the devastating floods that went through the Barlow center, Sushi Kosho is now back as good as ever with their unique recipes and presentations. Yay!!

The food and service here are outstanding! In addition to miso soup which was a cut above the usual, we shared the red dragon roll, the house roll, and the 15 spice ribs and all were just absolutely delicious. This place is definitely a local gem. We're lucky to have this wonderful chef and restaurant in our community.

Tops the charts for fresh nigiri/sashimi in North Bay. Also tops the charts by being prepared in slow motion.

Excellent sushi spot in the North Bay. Great toss sit at the counter watching the food prepared and chatting with the owner/chef behind the sushi bar. Melt-in-your mouth delicious sashimi and terrific hit foods and desserts as well. Definitely leave room for the panna cotta!!

This stunning new shop serves up some of the freshest and innovative interpretations of Japanese classics we have experienced. Miso soup is rich and savory without being too salty. Sashimi and crunch rolls are a delight. The only disappointment was the spicy edamame, flat and unexceptional. Our server was marginally knowledgeable but eager to please. Recced for a hit out of the box, and can't wait to visit when they are in full stride.

One of the best Japanese/sushi restaurants in Sonoma County. Menu offers exciting alternatives to the garden variety sushi place. Servers are extremely knowledgeable around menu offerings plus sake.

Really excellent sushi, high grades for fish quality and freshness. They are utilizing unique approaches to things like wakame salad and their nigiri and rolls are superb.

Since I already posted a review elsewhere I will just say here that the food serving was half what you would normally get at a traditional Japanese Sushi restaurant. Definitely over priced for the size and quality of food. I would not recommend this place if you are a die hard Sushi fan as my family is.

The pieces of fish in nigiri were too small to taste the fish.
The rice was packed too tight.

As a result have no idea if the expensive fish was with ordering.

Other restaurants have equally good fish in much larger portions at the same price allowing you to actually taste how great it is.

We wanted to love this place- its a great location. The prices were high and the portions were small. The service was not excellent (Although our waitress was friendly and pleasant) despite the place being almost empty. Overall, unremarkable and lackluster, especially given the prices.

The meal was exquisitely prepared by Chef Jake. The nigiri sushi was wonderful and the Panna Cotta and the Matcha cake were out of this world. Chef Jake presented a novel dish, combining bacon and Mochi that was unbelievable! We have eaten here before and we were very impressed by the new decor. Much more intimate and warm. Will definitely come back soon.

The food was absolutely fantastic. Everything we ordered was delicious and beautifully presented. Unfortunately, the service was terrible. After taking our order, we didn't see our waitress again until the end of our meal. The gals clearing the plates and bringing us our food were way more attentive. We never were asked if we wanted refills of our drinks, which we would have liked, and once we indicated that we were ready to go, the waitress got the check to us very quickly. It was frustrating to pay as much as we did for a delicious meal and have the service be so terrible.

What a charming restaurant. We are glad they reopened after the floods. We went with friends and while we made use of our extraordinary long wait for our food by catching up, I wouldn’t want service to be that slow next time. Carrot in the center of the roll wasbig and maybe better julienned in the roll.

The food impresses me. The dishes, especially the dressings and soup taste hand made from fresh ingredients. In Most Japanese restaurants the miso soup tastes identical like the typical Kikkoman mix,not here, it had lovely little mushrooms and a lightly salty fresh taste. Had a Japanese eggplant appetizer that had a wonderfully earthy mushroom sauce. We love the sesame spinach appetizer with its light dressing. The sushi rolls were very good made with brown rice and well chosen fish. They do not try to overwhelm me with a million different ingredients. I had the chirashi which had a nice variety of tasty fish, excellent crisp tsunomono on a bed of brown sushi rice. This has become our favorite Japanese restaurant.

I thought the food was mostly flavorless (especially the Seaweed salad and Miso soup) and the prices way too high. I have been going to Sushi Tozai and Hana (Rohnert Park) for many years, was excited to try your place. I was disappointed and won't go back. Nor will my friend

Probably the best sushi in Sonoma County. It's pricier, but worth it. Extremely fresh fish. Wonderful sticky brown rice (never had that before). I rated the noise level as high because it was a Friday night and the Barlow was hopping. I've eaten there at lunch and it's very sedate.

The non-sushi offerings were creative and delicious. From the seaweed salad to the pork belly, each were tasty and beautifully served. We had the chef’s choice of ten pieces of sashimi which was good, but the least delicious. Next time, and we will defiantly come back, we’ll be a little more careful in selecting the sushi.

We got there right on time for our reservation. We received our food one hour and 20 minutes later, plus they forgot the gyoza. Far too expensive for what it is.
