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.

Poor service - long time between courses. Very expensive for what you get.

Excellent fish, perfectly prepared and presented. Cooked dishes are superb, including miso black cod and the Japanese pancake. Wonderful experience!

Not good. After paying $39 per person, we were still hungry so we had to eat again at another restaurant.

Miso with Enoki mushrooms and tiny slices of green onions was a nice warm starter. We shared a Hawaiian Poke rice bowl, nice and fresh, plenty for two. Next was a Spicy tuna roll with perfect mild heat and a Tempura Shrimp roll to finish our lunch, all perfectly fresh and tasty.
With the large garage door open, it was a little cool and breezy. Our server was a bit overwhelmed and brought us the wrong order, we advised him as soon as possible and got it to the correct customer.

Sushi Kosho has downsized since the flooding that closed the restaurant. It is still a very welcoming elegant casual dining venue. The quality of the fish is excellent. The sushi rice is uncomplicated but not as flavorful as the best sushi I have had. The sushi is prepared with a little wasabi on the rice underneath the fish (not my favorite given that wasabi is served with the sushi and I would have gone lighter) and is served with pickled ginger and wasabi. Soy is available on the table. We had the restaurant night dinner that started with very good miso soup and a memorable seafood salad and included sushi, sashimi and a tuna roll. While quality of fish makes this the best sushi in Sonoma County for me, it does not compare with the best sushi restaurants in SF because it does not offer complexity in seasoning and light complimentary sauces applied to the sushi by master chefs. I do not usually use or want soy with my sushi when prepared at my favorite sushi restaurants but it was necessary here because of the lack of complexity and relative blandness of the rice. 4 stars for best fish quality in Sonoma County.

It’s fresh and delish with unique combinations of the rolls. Delish!
Service was prompt and pleasant. Nicely set tables with crisp linens and great dinnerware pieces.
Great experience.

Great service. Food is middle of the road for sushi. Well presented. However, it on the higher end of pricing. Although promised otherwise, not many options for GF folks. Overall it's good.

Food service was terrible : (
When we were in front, no host/hostess wasn't there , even waitress never greeting in 10 min.
Food was good, but it took 40 min to serve for sushi is not good..

Really great food and our waitress was awesome. Getting seated on the other hand was quite bazaar. The hostess treated us with “be with you in a minute.” I had a res and expected her to come back but she never did. She cleared tables, went to the bar, and basically left us standing at the hostess station for 10 minutes. Another group walked in and also got the same greeting until they grew impatient and walked to her and were seated promptly. I was there first so of course this made me follow suit. I was told “I could sit at the table by the open door when there were other similar tables in less drafty locations. I suggested another table which we were aallowed to seat ourselves at. I was happy when our waitress took over and we had delicious food and great service. Hope this hostess reads this review and clues up to satisfactory customer service. I will be back.

Very small portions. A portion of my chef's shashimi was tough. My partner's cod came with some unappealing white sauce under neath it. Overall, the value to price was just not there. Disappointing given that there seemed to be more staff than quests. Also, the place was loud given that there were next to no quests. The tables are too close for intimate dinners.

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.

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.

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.
