This place has amazing sushi. I've gone half a dozen times and never been disappointed. We live nearby and order take-out regularly. The fish is always so fresh! The only warning is that the spicy tuna roll is outrageously spicy - it will burn your tongue! So if you can't take the heat, don't order the spicy tuna roll. Everything else is perfection. read more

I've been here twice and always left hungry. The food actually is fantastic but alittle on the pricey side (the miso marinated cod being my favorite) I recommend it but it's not a place I would go frequently. read more

This place was so delicious!! I've been to a lot of different sushi restaurants in the Bay Area, and this one is by far my favorite. The fish was so fresh and the rolls were amazing. The price was totally reasonable for the outstanding quality and taste! If you love sushi, you owe it to yourself to check it out! Try the best roll...so yummy! read more

Koo is our favorite sushi place in the city. Good service and a nice selection of rolls. The fish is reliably fresh and prices are reasonable. read more

Dinner for 2 just over $100. Food is amazing, spec. the blue fine toro sashimi is one of the best in the city. Roll Recommendation: tokyo crunch and best salmon. Sake Recommendation: junmai small bottle. One of the few sushi places that is not only great but you feel full after you eat. Great date place. read more

The food was good but hardly filling. But you should have the Spoonful of Happiness because it is a culinary experience that lives up to its name. The sake list needs expansion. read more

I love the sushi and sashimi. Everything at Koo is so fresh, definitely a very good Japanese rest in the bay area.

I have been going to Koo since it first opened and it just gets better and better. My only complaint is that it's now difficult to get in! Fresh sushi, imaginative appetizers, great service and cozy surroundings. Can't recommend it enough. Just get there early! read more

This is one of my favorite Sushi restaurants in SF. Sitting at the counter is the best way to enjoy sushi, IMHO. Mirugai (geoduck?) is really good here, and they even have the TORIKAI shochu! mmm.. gotta go back there sometime soon. read more

My Girlfriend and I are sushi lover's and stumbled onto Koo near when it 1st opened I know cause the stain wasn't dry and it stained my white shirt. Usually I might be upset but the sushi family and the love to serve the best sushi ever straight from the soul melted my thoughts and heart into a fantasy and explosion of textures and flavors. We travel the world and still its great to come back to the best sushi place ever right in our own backyard! No matter how many times we go (every special occassion, bday, anniversary, etc.) the sushi is consistently awesome. Take an adventure let the chef take you away on a food extravaganza of fish and exotic creations. We love Koo we have been there at least as much as we can and its never too much and we never agree more that the time money and food is some of our best times spent. Never stop making the best sushi! WE Love You Koo!!!!!!!!!!!!!!!! read more

Great sashimi. Melts in your mouth and it's the perfect size. Their rolls and hand rolls aren't half bad either but I'd recommend sticking with the sashimi (either a combination plate or a la carte). Price is very reasonable too. read more

Everything has remained good quality here. But there are few thing i would like to share, when you guys are ordering take out, please make sure they can do it take out on your items. There are quite few my favorite dishes, the waitress there said "THEY CAN'T DO IT TOGO". I asked then why because I used to order it, and the waitress told me "The owner didn't like it." WOw....surprised!!! But anyway overall everything still fresh and tasty..just had an issue with the togo item. read more

Really authentic! I had been reluctant to eat Sushi in the US because, as a Japanese person, I always felt difference between American Sushi and Japanese Sushi. But, Koo's Sushi is as fantastic as in prestigious Sushi restaurants in Japan. In particular, I recommend to try spoonful of happiness, which can tell you "core of Japanese cuisine". read more

Yes it is pricey, but I think it is worth it. I love the sushi here and so does the rest of my family. I like to sit at the bar when we can so we can mingle with the sushi chefs. We are terrible at making decisions so we always do chef's choice and they have never let us down. The one thing I always do get though is the "spoon full of happiness". I always start and end my dinning experience with one of these little treasures. Get one yourself; you won't be sorry. read more

Great service. We were slow to order but didn't feel rushed at all. The organic tuna was soo fresh, melt-in-your-mouth and we really enjoyed the U2 roll. Went with my girl-friends, had a blast and bottle of vino (sauvignon blanc) went very well with a very satisfying meal. For SF, parking wasn't too crazy. read more

For those vegetarians who don't eat fish, this is the best sushi place in SF! Tofu Godzilla is amazing. The veggie combo plate is delicious. I like the warm house sake too. read more

Great sushi place. Definitely a must try. Fresh fish and nice service.

When I was living in Inner Richmond, I LOVED going to Koo. If sashimi is what you want, you gotta go here. The atmosphere is young, but not overly hipster. It's great quality fish overall, and the rolls are yummy too. The service is pretty good too ;) read more

Very fresh sashimi and sliced just like the chefs would in Japan. When your squid sashimi is almost translucent and tastes like the sweet sea, the chef is doing something right. Decent sake selection and unobtrusive wait staff. read more

Sat at the sushi bar and had a great experience. Everything tasted fresh and was high quality. I'll definitely be back again soon!

everytime we go they ask if we have reservations. um NO. then they bring us to a table that has a reserved sign that they remove upon seating us. i think they pretend theyre busy by having these fake reservation signs everywhere. our waiter was never paying attention us. i just wanted to go into the kitchen and help him bring my food out. so we ended up ordering a bunch of stufff: the best roll-was perfect. crab dynamite- the way to spend $7 on one roll, godzilla tofu- too salty and not to mention the size an ice cube, spicy tuna-great, salmon and tuna tartar- yuck, the shrimp chip it comes with is always stale and and its just not that good, beef tantaki- um could they leave it on the grill a bit longer? the mount fuji dessert was a lil piece of heaven for me. read more

I heard through many people that Koo was a pretty good sushi joint. Had a nice atmosphere. The food came out, and had nice presentation. The sushi was decent, but not really worth the price. But here's the kicker. We receive the bill drop our card, and promptly sign the credit slip. Not 3 minutes later, the waiter, which was completely unfriendly in the first place, came by and told us that he needed the table for another group of people. We asked him if he was telling us to "move along" and he smugly said, "well, yes." What a jerk! We adjusted our tip amount on the receipt accordingly and left. On the way out we couldn't help but notice that there were no people waiting . . . I think it is all about the service, and I don't think a sushi restaurant in the inner sunset can afford to give poopy service. I live right down the street from Koo and will never go again. read more

What a pleasant surprise! I used to go to Sushi Sho in Albany for the best sushi but for those of you who had been there, you know how difficult it is to get a seat. So I yelped and found Koo and have never returned back to Albany for sushi. Koo rocks! read more

1, the food is too salty 2, the rice of the sushi is a bit too hard 3, service is extremely bad 4, expensive we would say that because we reserved a table for 11 people, five of us went there first while our friends had a traffic jam, the waiters and waitress came to us and kept reminding us that we the minimum fee is 20 dollars per person and our maximum time is only two hours. They came to us for this for more 3 times with different people. they told us we should order as soon as possible because it takes a long time for them to make sushi. We all thought the sushi would taste good since it takes long time; however, the rice is too hard and salty. around 20 minutes to 2 hours, they reminded us that our bill is not enough for the minimum payment, and they said if we could order for 200 dollars they would still charge us for 200 dollars, and they never asked us if we have finished the dish, they took the dish away. they also took my friend's plate away until my friend said" I didn't finish it yet". It was one of my friends' birthday, we gave her a birthday cake, but we never said we would eat the cake there, the waitress reminded us again, if we want to eat the cake there, they would charge 2 dollars per person. If you want to go there, then go, experience their bad service and bad food, and then give us your comments. Never go there again, if you have the same experience as we did. Good luck!!!!!!!!!! read more

Good food. Its in the top 5 in the city though. Its not a cheap joint, but have fun and enjoy when you can.

okay. I found my sushi joint. Too bad it's 3000 miles away. two nights in a row. wow. unagi unagi unagi.

care for brunch ? check my next review *** mediocre ... 3.5 (ok, i'll be nice) ... the service was truly incredible ... can't say any more ... a modernized sushi place ... it's quite fascinating to me how sf can be so segregated depending on where you stand on the grid ... so you're thinking, "irving..." given that i AM asian who doesn't stick with my asian roots at all times, crossing 19th ave on the other side is predominately white ... and if you cross the other side going towards the ocean, they're all asian ... so soo weird. why can't we all be happy and mingle together? *no pun intended* koo is located centrally in the white section of irving ... koo ... we sat at the sushi bar w/ressies, and had a great time talking to the owner and the other 2 sushi chefs ... upon walking in, the younger looking guy who was onto the far left pretty much made sushi for the rest of the patrons on the general dining area, while the middle guy and the one on the right made sushi for the ones sitting at the bar ... the owner, however is a long time sushi chef, or so he implies ... he initially opened Koo 4 yrs ago, and prior to koo, he was also the owner of ace wasabi and helped out with sushi ran (which isn't exactly my favorite as well: http://www.yelp.com/user_details_review_search?userid=EKdyI4jpUF29YtPkKiCtcg&q=sushi+ran) which is located in the marina ... he mentioned how he didn't really like the marina crowd since it was more of a hang out place with "good looking people" looking for "other good looking people..."while koo was a place for folks who really wanted to eat authentic japanese food... as a marina resident ... my initial thought ... "i suppose... i guess the marina is the marina for a reason" lol i must say, the extra star DOES in fact go out to the fact that this IS japanese owned, and not korean or chinese owned ... we spent almost $200 on mediocre sushi ... there were some catchy specials and i must say, their nigiri ?? ive had cheaper ones elsewhere and it was byfar MORE fresh ... their specialty rolls were a hit or miss. the flying kamikazi was super yummy, but their tokyo crunch and their azteca wasn't that great ... the head chef (owner) highly suggested us getting a spoonful of happiness (what a cute name) which entails a spoonful of Uni, Quall Egg, Tobiko, Ponzu & Ankimo wrapped with whitefish, Truffle-Oil & a shot of chilled Sake for $10... any choice of the sake... this sake we had was called suigei tokubetsu junmai, which is $7 normally... very flowery for the nose... they also have a wide range of other sakes, wine and champagnes ... the spoonful was definitely a delight! i'd say if we spent almost $200 on sushi, i personally would've hooked my people up with free dessert or something.. maybe i'm just asking too much.. but i can tell you, that this seems to be a local favorite because the very few folks who did trickle were on a name basis with the owners, and i in fact, witnessed the owner hooking one couple up with free drinks and discussing their trip at hawaii ... they UNFORTUNATELY don't take online ressies ... good luck! read more

I've been to Koo a few times because it's one of the decent sushi places in my partner's neighborhood. Decent, meaning the freshness of the fish is inconsistent and the prices are too high for the quality. But, in past visits I felt it was an enjoyable-enough experience to come back. We went there last Thursday for dinner, and there was an obviously newish host working. He took a bit too long to greet us and then seemed confused about where to seat us (we had a reservation). Before ordering, I asked the waitress for recommendations on rolls, since I usually order nigiri or sashimi. She pointed out to me the most popular, meaning most ordered, rolls on the menu, which are the rolls including fried things/tempura, or the more Americanized rolls. Being raised with Japanese culture, I was disappointed by her recommendations. We enjoyed our decent meal though, and were paying our check and finishing off our second bottle of sake. Then, the host came up to us and said something to the effect of, "I have another reservation waiting for this table. I'm not asking you to leave, but just consider that." Mind you, we had not taken our sweet time with this meal, in fact, we were on our way to an event so were aware of being timely and our total time in the restaurant was still under one hour. What bothered me more though, was that we were seated next to an older, more Caucasian couple who had been there long before we had arrived by the looks of where they were in their courses when we sat down, and nothing was said to them by the host. I felt discriminated against, which is really unacceptable especially at a place with such high-end prices (we spent over $100) and attitude. I won't be going back. read more

wonderful sushi, nice atmosphere, great service, and right around the corner from my house- fantastic!

super yum. great sashimi, creative grilled items, lots of sake choices. among the best sushi i've had in the city. right up there with zushi puzzle. helps they have good service and their lamps are not eye-bothering. read more

This place is solid , albeit off the beaten path. We walked in and the hostess couldn't have been more gracious. It's the perfect spot to catch up with friends or have a date, especially with the low lighting and generally cool atmosphere. Prices are reasonable and there's good-sized portions. For a group of 3, we started off with the Scallop / Shrimp dumplings and Butter Lettuce Short Ribs (on the "share" menu) which were really tasty. You get solid mouthfuls and I was already feeling somewhat full. Next came a sashimi plate with 4 different types of fresh fish. Lastly, we had two rolls, the Azteca and Flying Kamikaze, both very tasty and at a good fish-to-rice ratio. We didn't pass up on dessert and got the Mt. Fuji with ginger gelato, which was refreshing. If you're a chocolate lover, I'd say get your own Mt. Fuji (all deserts were around $4, plus $2 for the ice cream). Solid dinner at about $31/person with tip included. read more

dizam. some of the best sushi i have eaten. super fresh fish, the perfect temperature of rice, scrumptious rolls, melt-in-your-mouth nigiri. great service and atmosphere tops it all off. coming back here FOR SURE. read more

one of the best sushi restaurants in SF! +1 star from being walking distance from my house and being open til 10 or 11pm :D really helps when my random sushi cravings kick in! the food is delicious- so fresh, tasty and generous! it is a little pricey, but the quality of the raw fish and other [cooked] tasty items on the menu, it's worth every single penny and then some! i'm a stickler about service in asian restaurants, and this place has attentive, thoughful and courteous servers, the owner's wife herself walks around checking on customers and even chatted my friend and i up. the tuna and salmon tartare is awesome, though the one at tokyo a go go is better. spoonful of happiness is great, except i don't drink sake, and they have best ankimo ever!!!! i also never like uni until i had it here, damn that spoonful of happiness!!!!!! but now apparently i eat uni, lol. for dessert, the mt. fuji is a MUST HAVE! CHOCOLATE CAKE STUFFED WITH WHITE CHOCOLATE MOUSSE? HEL-LO! the only thing possible that would make the restaurant even more perfect is if they serve mirugai and ankimo on the same night. MMMMMMM. i would be here everyday if that happened. read more
