Warning! Restaurant has the same menu, but it has changed hands and it is not the same! This was our favorite restaurant, so we were very excited to see it back open after a brief closure & sale. However, we were sorely disappointed. Our rolls came out with imitation crab laid on top and the minced crab in the rolls tastes fishy with a horrible texture. Likely they are using imitation crab instead of the real crab they used previously. The complementary miso was great & given to you with the standard salad, which was nice. The new staff was also very welcoming & friendly. For these two reasons, I upped the rating to three stars. Veggie tempura tastes good, but greasy & less pieces than you would receive previously. The Japanese mayo has significantly turned up the heat. My husband can't do spicy, so this was an unfortunate surprise. The menu is the same, but things are very different. read more

My husband, son, and I are big sushi lovers, and O'Sushi Restaurant has long been our favorite spot. A little over a month ago, we were sad to learn it was closing, but thrilled when we heard new owners were taking over while keeping the beloved O'Sushi name. We were eager to see if the quality would remain the same. Yesterday marked our second visit since the change, and we couldn't be happier. I tried the Sashimi Salad, and it was absolutely delicious. My son loved his shrimp tempura roll, and my husband has enjoyed every roll he's ordered so far. The chef was incredibly friendly and even brought us a complimentary appetizer that was fantastic. When we asked how the restaurant is doing, he mentioned it's been a little slow, but we truly hope this wonderful place stays afloat and receives the public support it deserves. The new owners are a very sweet couple, and the warm, welcoming atmosphere makes us want to keep coming back. If you love quality sushi and great service, I highly recommend giving O'Sushi a try--you won't be disappointed! read more

O Sushi is open with new ownership. We have been twice and the new owners are so nice and still making great food. Tonight they were so fun, having us try some grilled salmon and doing a funny birthday song and bringing over Mochi. We will be going back regularly. Read a review from a few weeks ago: our first time back they were still getting things dialed in but this second time was great and way less greasy tempura. read more

O! Sushi is a great spot with wonderful service and great food! We've been going here for years, and were worried about the change in owners, but the new owners are so welcoming and kind. When we went today, they gave us miso soup, a salmon dish, and deep fried oreos, all on the house! The atmosphere is usually calm and quiet. The food itself is delicious as well as presented beautifully. I would definitely recommend O! Sushi. read more

Maybe the overall best Sushi restaurant I have been to in the US. Very friendly service. High-quality sashimi and nigiri! Shockingly big portions (in the age of shrinkflation!)! I had a mixed sashimi/nigiri plate, which was just great (2x6=12 pieces for $25!) My kiddo had a be to box, which was a little less impressive - maybe the chef is focussing on the rolls - but still good and good value. We were given a free dessert, thank you (no mochi, though = -0.1 star deduction). read more

The service is as expected with kind, attentive, and helpful people. Typical strip mall ambiance. The food is of quantity, but not really sushi in the sense of great cuts of fish, but more along the lines of lots of rice wrapped around things, American style. The soy sauce is salty as the salt flats. I mean too salty. Enough to ruin the food. I've mentioned that to them before, with no changes. I think they keep it salty, so you get more drinks! The one thing that pissed me off was the tipping calculations which are done on top of the taxed amount, not the food/drinks alone. If you use their suggestions, you are tipping on tax as well. Why this bothers me? Because the POS software lets you choose which approach you want and they chose to take more. That will cost them in the long run. Also, it's dishonest in my mind. read more

To be honest i don't know if this place changed hands or not but i had an amazing dinner, Service was spot on, food was great. I loved watching the sushi maker. and I was all by myself.. 5 stars read more

Excellent food....always!! Friendly staff and reliably delicious. Chicken teriyaki is delicious!

One of the best options in Petaluma. Great food and quick service. Always enjoy this place!

This sushi restaurant has a good rating for a reason! The sushi is incredible. The menu has so many options, and the server/server assistant were very polite. The setting is clean with elevated ceilings which makes you feel like you have enough space to enjoy your meal. They also offer the option of sitting at the bar top to watch the chefs make the magic happen. 10/10 would highly recommend this place if you are looking for quality sushi. With Gratitude, Vanessa read more

O Sushi - 2 item Bento Lunch - Sushi Bars Near Me - Petaluma, California

This used to be our go-to sushi spot. Unfortunately, their good sushi chef left a couple of years ago and the sushi just gets worse and worse each time. The fish isn't cut well, but worse than that, the sushi rice is terrible. It's like bad grocery store sushi that's been sitting in a refrigerator all day. The rice is hard and flavorless, like the sushi chefs don't know how to make sushi rice. We didn't even eat most of our sushi. Their cooked food is still good, though, which is why they still get 3 stars. I recommend them for food from their kitchen, but not for their sushi. read more

Thanks to hubby for introducing me to this wonderful sushi spot, it's our favorite date night restaurant. Ironically, hubby has introduced me to many places throughout the years; he just stays behind the scenes. Hoya the sushi Chef is very personable, chat it up with him sometime. He can make anything you want upon request. The hand rolls are extremely fresh, and the sashimi is glistening with perfection "oh my COD"! Staff are attentive, refilling tea and water constantly. The service is on point with complimentary fried oreos to boot. What a nice way to finish a lovely meal. They take a mid-lunch break at 230pm and reopens at 5pm for dinner. They're closed on Sundays. There's ample parking in this shopping plaza known as the Osh parking lot to many OG's. 'Til next time ~ cheers & see you on Yelp (SYOY)! #discoverpetaluma #supportlocalbusinesses read more

Excellent food and excellent service! Definitely recommend to all sushi and bento box lovers!

Got 2 salmon rolls, a miso soup, and a sushi rice and was pleasantly surprised to see the quantity of food for the $20 I paid, especially in the salmon which was amazing quality. I walked in to make a takeout order and the staff was very kind and offered great service. The restaurant was very nice on the interior and there was some nice little chairs to sit at while I waited for my food, the dining area looked nice and I would definitely eat there again! read more

Amazing spectacular food and such kind hearted sweet amazing hard workers. The food was amazing quality and very fresh it was the bomb. The servers were very amiable people. My favorite sushi restaurant in the county, I recommend it to everyone who loves sushi. Amazing service and kind mannered people. The Restaurant was super clean with Tv's for entertainment. Amazing Restaurant overall. If I could do more than 5 starts I for sure would! read more

This place is a family favorite. Their rolls are always fresh and tasty and the service excellent. I prefer the rolls to the bento options. I do miss the complimentary soup and salad but understand with the cost of everything increasing. Wish they would bring back the pineapple at the end of the meal vs the deep fried Oreos which I'm not a fan of but my kids gladly take me serving. read more

Lots of options for sushi in this area, but like to try new restaurants. Place was packed, which is a good sign. Quick service. Good food. I got the apple sushi roll. A little fishy, but beautifully prepared. Prices are competitive. read more

My mom and I love this place. It's our go-to. I've been to other sushi places in Petaluma and wasn't impressed. But O! never disappoints. Our favorite roll is the Spivey Crunchy Roll. Employees are always polite and attentive. read more

New favorite sushi spot!! Seriously loved the Bay Bridge roll. We will be coming back!

Food was good. Prices seem high, but everything is more costly. Lunch server was a little slow. Would like more taste in my food. Could improve, but then nothings is perfect. read more

This was a go to spot for my lunches. Ordered the bento box with chicken teriyaki and tuna sashimi. Got a good amount of food for the price it was at. Got a side of edamame beans, salad and miso soup. Staff was friendly. Definitely recommend to come here for lunch if you're in the area. The bento box comes with 3 choices rather than just the 2 for lunch. read more

There was only one other couple in the restaurant. I had to go to the kitchen twice to ask for service. I ended up with food poisoning. the restaurant next door is excellent. The waitress cleaned up the table next to us making a lot of noise. Prices are too high for what you get. read more

I've been here three times and each visit did not disappoint! I've tried numerous sushi rolls, bento box lunches and dinners, miso soup, everything always tastes so good!

This restaurant is a must if you enjoy great sushi! read more

I cant seem to veer away from the spicy sashimi salad. It's so delicious and a reasonable price for what you get. Every ingredient, esp the sashimi is super fresh and the flavors are spot on.

O Sushi - bento box with shrimp tempura roll and salmon teriyaki - Sushi Bars Near Me - Petaluma, California

I ordered four rolls from O Sushi tonight -- the Toto, Lion King, Baked Scallop, and Jack & Jill, and had a pretty good dinner. For four people, the four rolls and sides of miso soup were more than enough food. I thought the fish used in the rolls tasted pretty fresh, and I appreciate how quickly the food was prepared once I placed my order over the phone. The staff here seemed very nice when I arrived to pick-up my order. My only nit-pick comment about O Sushi is for the rolls that we ordered, I thought the rice was packed a little bit too tightly, making the rolls a little bit too dense for my liking. read more

The best Sashimi and Sushi rolls! Service is excellent. Great place to eat! Highly recommend! read more

This was a good stop for sushi. I think for the money they are really good. I think citing speed of service as a negative sounds weird but seems it may have affected quality a little. Gave me the impression that some of the items are prepared ahead of time. We were there for lunch so no big deal. Would return. read more

The service was terrible. The staff was afraid of the owner & seemed to walk on eggshells. Apparently they couldn't make any accommodations to the menu. It was a terrible place to eat. I wouldn't recommend it at all. The quality of fish, crab, etc... was of the lowest quality I've seen in a long time. The owner (I'm assuming) an Asian woman was very rude & yelled at us to leave the restaurant because we complained about the quality of the dishes brought to our table. I tried to speak w/ her again to try & find a mutually acceptable agreement re: the bill & she again yelled directly at me to leave the restaurant & I willingly complied. read more
