Eilien L.

This is our go to favorite izakaya in Sunnyvale. Love the ambience, very cozy and they open late. Which perfect for us, corporate slave haha. We ordered sake maki, tempura udon, Galbi skewers, oyakodon, and katsudon. The food portion was large with good quality for the price. Will definitely coming back for more!!!

Karaage Chicken
Pranathi B.

*USP: Korean and Japanese restaurant with an extensive menu covering bibimbap to udon and rolls to bento boxes and skewers. *Ambiance: cosy restaurant with a huge mirror along one wall and Japanese style paper lanterns on the ceiling. *FOOD: we tried a little bit of everything and across the board the food was kind of decent but not memorable. Chicken karaage: the batter on this one was weird. It was more like popcorn chicken and very greasy as well. Our family normally tends to clean this dish up in a few minutes but here there was a lot left and no one wanted more after the first serving. Bento box: nice way to try a lot of dishes, we got the veggie rolls as one of the sides and it was good. Nabeyaki udon: strong flavor of unwashed chicken. Not very enjoyable. Bibimbap: this one was difficult to eat and there was no cohesive element binding the individual components all together.

Koko Izakaya has a great atmosphere, and the vibes are just right! As mentioned on their menu, "A PLACE WHERE GOOD FOOD, DRINKS, AND PEOPLE COME TOGETHER." It's located in the Hacienda Center plaza between Marie Calendar's and Michael's. 4.5 rounded up to 5. SERVICE This is the only area needing improvement. Usually, only two servers are present, and water refills or check deliveries aren't quick. We've had to wave down servers twice to settle checks, though we weren't in a rush. We also heard a table next to us waiting impatiently and loudly yelled, "excuse me," to get a server's attention. FOOD - Takoyaki - Bento Box (spicy pork and chicken katsu) My partner and I ordered bento boxes the first time we visited. It comes with soup, salad, and a choice of sushi. There are several protein options. The portions are generous for the price, and everything was delicious and enjoyable. On our second visit, my party ordered quite a few items to try, and everything was tasty! The Flamin Dragon roll was set on fire while in foil and left for two minutes, which added a fun element to the experience. - Galbi Korean BBQ Short Ribs - Skewers: Chicken Thighs, Asparagus & Bacon, Rice Cake - Special Sushi: Caterpillar, Flamin Dragon Overall, it's a great spot to grab drinks, enjoy good food, and have a good time. The vibe is super chill.

Quality of the food was a lot better than expected. Mentaiko pasta recommend. Service is good

One of the few places open later in the area. Had a lot of different choices on the menu but also a lot was sold out. The food was overall decent. A good place for a late night meal.

Nice to see another Izakaya spot pop up in Sunnyvale. This one has an extensive menu. Also lots of Japanese influences in the decor. Nice aesthetics. Clean and organized. Tried some of their skewers and plated items, including their garlic steak and grilled fish (saba). Food was tasty. Izakaya is generally not cheap but what's nice about it is you can order a bunch of small plates to try a wider variety of items. This restaurant is in a plaza that also houses Michael's and Safeway. Large shared parking lot is available.

Good oysters, very generous with the lemon slices, makes it look cute too! The cocktail sauce is balanced.

Chicken Gizzard
Colin S.

I really enjoyed the chicken gizzards, and the ramen broth was full of flavor. The restaurant had a great atmosphere, and I love that they're open until 11 p.m. It wasn't too crowded when I visited later in the evening, which made the experience even more enjoyable. It's a great spot for a relaxed, late-night meal!

Wendy T.

The service was good. It has sushi rolls & beef tofu soup was pretty good. There wasn't much options for the skewers. I ordered the chicken gizzards & hearts, they were dry & hard. No bueno. They offer happy hour for mainly the drinks & tofu soup.

Overcharging tips
Dustin K.

Very unhappy with our experience at Koko Izakaya. The suggested tip amounts printed on the receipt were significantly inflated. Our pre-tax subtotal was $121.00, so a 20% tip should have been $24.20. Even calculated after tax, using the total of $132.80, a 20% tip would be $26.56, not the $31.16 shown on the receipt. Customers should check the math carefully before paying. The food was also mediocre and overpriced. The unadon bowl seemed to contain roughly three servings of rice for every one serving of eel. The seafood udon pasta arrived with about half of the clams and mussels still closed, which made us uncomfortable eating them. The restaurant offered to remake the dish, but the replacement had the same problem, with about half of the shellfish still closed. Between the inaccurate tip suggestions, high prices, and disappointing food quality, this was a 1-star experience.

Jamie S.

Definitely not impressed. When we walked in, we were pointed to a table. Not led to one. Pointed to one. When we said we needed a bit of time to look over the menu the server rudely told us: "order from the tablet then. It also has pictures" Well...as you can see from the pictures below, no pictures were on the tablet menu. Our appetizers came. Miso soup was warm, not hot and overwhelmingly salty, which meant it was not fresh. And there were no tofu pieces in it. Gyoza was the same story. Warm, not hot. I've also never have described sushi as "puffy" before, but my Philly roll was OVERLY caked in rice. Also all fish tasted off, so the fish was not fresh as well. This is the first time my partner and I left food on the plate. At no point did any staff check on us. I had high hopes for Koko. But we will definitely not be returning.

Rolls a plenty. Baked fancy rolls better, sashimi topped rolls a little too brave for the quality of fish.
Lawrence M.

I wanted so much to like this place. Cool rock n roll sushi vibe, everything looked new, lined up sushi bottles. Nice posters of sushi and donburi in the window. The menu was good, but turned out to be too good to be true. It had some traditional items. We actually came in for Curry Chicken Katsu, which was quite decent. Katsu was nicely breaded, curry was fresh and flavorful. The hot bowl had a Hawaiian looking item: the Spicy Kimchi Tuna Nabe. Or was it just some Korean fusion mashup. Anyways, I asked the guy, and he said it was a popular item. So we tried it out. The thing was more like tofu hotpot, with tuna chunks thrown in. It had glowing red hot oil floating on top. Even with rice, it was a little too spicy for what you'd expect in a Japanese bowl. We didn't finish. They had a lot of rolls, too, so we tried the 3 roll combo. Not bad, not great. Saved $10 off the three. The Jalapeno Bomb Roll was a baked spicy tuna thing, with a creamy topping. I liked this the best. Sexy cassanova and El Camino were more like spicy tuna rainbow roll variations. I guess we were tricked into buying 3 fancy rolls, and we were pretty full. When finishing up, I tried deconstructing the rolls, to eat the "expensive" parts. I have to say, eating the fish itself, sashimi style, revealed the mediocre quality of the fish. Dunno, if you like innovative fusion places, with a fun vibe and friendly service, come give it a try. But looking for familiar dishes, with good quality? Maybe not on a midweek night.

See all

Reviews are largely positive. Many highlight the fresh and flavorful food, cozy and lively ambiance, and friendly and attentive service.

We had the budae jjigae and mul naengmyeon…read more The stew had lots of fermented kimchi flavor. If you like that, this is great. My preference is basically a shin ramyun which has a thicker broth. I loved how this had tteok, sausage, and spam. It's also wonderful that it comes out still boiling inside the stone pot. I love their fresh, sweet kimchi banchan. The place is nice and clean and the service is friendly. It's nice that they also have private rooms available.

The decor is a little dated. Service was efficient and met expectations. We ordered Wang Mandoo, LA Galbi, and a Cold Noodle Combo. The Wang Mandoo were described as king size boiled dumplings with beef, pork, and kimchi, and the sizes did not disappoint -- indeed very huge, even larger than the mandoo I've had in Korea. The meat was tender and overall very tasty. The LA Galbi came out as large slices of BBQ short ribs and were tender, juicy, and flavorful. The cold noodle combo came with cold noodles in broth plus bulgogi. You can pick other protein but that's what we chose. The cold noodles were refreshing and the noodles were chewy and bouncy. The portions were fairly large. The bulgogi was probably the most disappointing of all the dishes we had. It was tender beef but lacked some bbq flavor. I appreciated the wide variety of Banchans that were brought out to our table. They also gladly refilled the banchans as needed.

All their korean food is delicious and authentic! My go to spot for mul naengmyeon and galbi! So so flavorful and always hits the spot! Bossam is super delish as well, perfectly cooked. Cabbage and sides go well with the dish. Japchae is a standard dish. Seafood pancake is on the thicker side- wish it was a little thinner and crispier, but appreciate how much seafood they stuff it with. Standard tofu soup. Restaurant is big and spacious. Quick service and turn around. They get pretty busy and the korean ladies will def put that check on the table asap and kick you out when you look like you're done eating haha. Nothing that I take personally, lots of customers to feed and lots of banchan dishes to fill up!

It's convenient to order on the iPad at the table. It's a good size, well lit restaurant with lots of seating (tables & booths). Every time I've dined in, it's been busy, so be ready for a wait! Great customer service. Parking gets crazy in this plaza!

It's my 3rd time here and the quality of the banchans and food has remained consistent. I've tried the mixed tofu soup, Wagyu Galbi and this visit I tried their Wagyu bulgogi. Also tried their appetizers: snow crab twigim, black cod twigim. These were fried well and came with 2 dips- preferred the garlic one. Appetizers are a good portion to share between 2 people but more than that you'll have to order extra. Everything was seasoned well. Love how they have a banchan cart that comes by regularly to refill any banchans you want. Service is great.

TLDR: Expensive, taste is ALMOST worth it…read more This place is CRAZY expensive. Even with the premium ingredients, it's still a little bit overvalued, I think. Unlimited banchan.... lots of places has those. Some of the banchan are little-seen in other places, yeah. But I feel like most of the menu is there just to upsell... So take for example, the wagyu Galbi, which was $58. Did it taste good? Yes it does! The meat was tender, and it had this great sauce, which I loved. But the wagyu was completed wasted on it. ANY good piece of beef would have tasted just as delicious... because of the sauce. My wife ordered the Wagyu Tofu Soup. Again... I feel that the wagyu is wasted on this dish as well. It's going to be all tender and mushy from being in the soup anyway. Any beef, almost any cut would have done here. I really liked their seafood pancake though. It's not as mealy as other places. In fact, it tasted more like the Chinese onion pancake... crispier. I really liked it. I wouldn't wait 2 hrs for it though, nor pay $18. If this sounds like I had a negative experience, I definitely did not. The food itself was well cooked and in ways I haven't experienced in other Korean places. The service was really great. The servers monitored our water levels, banchan levels. And despite the full house, the service and meals were quick. BUT... this place has a few cons as well. Unnecessary (IMO) premium ingredients, no reservations, LONG waitlist (even though we were put on the waitlist at 6pm, told it would be a 1.5 hr wait; we still didn't get seated until 8). It just keeps this place out of 5 stars for me, sorry.

When i needed to reschedule, no one answered the phone (i called 3 times in 2 hours). I texted their number asking them to reschedule and they replied and rescheduled ! They have a small-ish parking lot in rear. The staff are all friendly and professional. I'm a ban chan snob and their ban chans are sooo good. I also think their short rib and brisket are delicious. The server cooks the meat for you, and if you need a servers attention, you ring the bell and they show up immediately. When you order meats to grill, soup comes with it. On my first visit, the soup was forgotten. On my 2nd visit, I tried hard to remember to about the soup, but in doing so.... I did not realize that they forgot my Pajeon pancake side dish! I didn't realize it until I got home and I was so sad. If you go, they will most likely forget to bring out a side dish that is included with your meal (and the meal isn't cheap!). so please learn from my mistake .

We ordered 3 servings of purple rice but they were out of it, but still charged me for it on my bill (which I didn't realize until after I left the restaurant). As for the bbq entrees, the chungdam galbi is consistently my favorite galbi out of the 3. If you like savory more than sweet, then you would probably like the best seller yangnyeom galbi more. the brisket was not notable at all, which is consistent with my previous experience of ordering it in the past. the beef tartare comes with nori that you scoop the beef tartare on top of and eat in one bite. It was good and I did enjoy it, but I don't know if I liked it enough to order it again in the future. The seabass was also good and flavorful. Other ingredients in the dish included rice cake, tofu, and radish. I would be down to re-order the sea bass again in the future just so that there's an entree on the table that isn't meat. As for complimentary banchan, there was raw marinated crab, fish cake, potato salad, kim chi, marinated/fermented spinach (?), and another pickled vegetable side dish that I didn't know the name of but it was yummy.
