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.

We showed up for our reservation and were told they could not accommodate us. Will not be making another reservation in the future, despite previously wanting to try it.

This was our second meal at Kosho and it was as good as the first. The sushi is fresh, flavorful and very reasonable. We had several rolls this second time and they were all amazing.

Our friends had draft beers and they said they were excellent! The wine list has a very nice selection and we enjoyed the Chardonnay we ordered.

All in all, we were very impressed and look forward to our next meal at Kosho!

Sushi Koshō is always excellent. The food was extraordinary, the service on the patio was fantastic and I can’t wait to come back. Definitely worth the hour+ drive from San Francisco!

Loved the service and the owner is always attentive! We were there several months ago and the amazing server remembered Bud coming there as his first “outing” after 4 months in the hospital!

Love it and so glad you can still hang in there with all the challenges you’ve faced!

The short ribs were very tasty as was the eggplant appetizer. The portion size for the eggplant was too small - it was a small Japanese eggplant cut into 4 small pieces. The taste was heavenly but portion size too small given the price. The sushi was good not especially unique.

Always had a great experience there however this time it took almost an hour to get the sushi rolls part of the the dinner because they had 2 really big to-go orders and the sushi chef was too busy to make our order. We were 4 people and two got their cooked dish and salad very quickly and the rest of us watched them eat and had to wait way too long for our food. Better get organized as that was not the best experience.

So grateful that Sushi Kosho is now open for patio seating and service. I met three friends there for my birthday and we had a fabulous time. Our server Nicholas was fantastic and the food was incredible. I highly recommend the wild mushroom salad, the double down roll and omakase sashimi!!

My first time dining out since SIP - the food was incredible, our server was kind and made us feel welcome, and tables were spaced out enough.
The only downside was that our table, being outside in the Barlow, was basically in a public walkway so we had random strangers coming within inches of our table a few times throughout our meal. Since we went on a Monday, there wasnt too much traffic but I can imagine it being really bad on weekends. BUT its really just our one table thats in the walkway so its easy to avoid.

We'll definitely be back!

As usual, Sushi Kosho did not disappoint. They have appropriately spaced out their tables, more so than many resturants have room to, and even added tables outside.

I went with my goto dish here: chirashi bowl. It is still fantastic.
Check it out, but don't forget to try various nigiri too! Fine Japanese in Sebastopol.

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.

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.
