1-restaurant, it was located in a shopping center with plenty of parking and easy to locate. The space inside is a good size and perfect for a quick bite or with family and friends. 2-service, the staff was quick and friendly. They attended to us quickly and checked on us multiple times. 3-food, the food was good and fresh. It aligns with all other sushi places I've visited, they have both sushi and Japanese cuisine. There is an AYCE option as well as lunch/dinner specials. read more

This my 3rd time ordering from Koya Sushi. Sadly it was not up to par today. I ordered it via Grubhub and it came on time so I don't want to blame the driver. I ordered two teriyaki bowls, a Fontana roll, and an Alaskan roll. What I think happened was the sushi got to warm because they bagged it with the hot teriyaki bowls. The sushi was warm, there was no chill to it and sadly that compromises the taste. But it wasn't just the taste, it was the overall presentation. If you look at past photos and the current photo I posted you can see the difference. It was a lot smaller. The avocado was brown, and it tasted warm and slimy. The teriyaki bowls were just fine! It's a great value and the portion is huge. The chicken is nicely grilled and the sauce they use isn't too sweet. I do add kimchi to mine because it needs some freshness, crunchy, and acidity because there's not veggies. read more

I don't know why this restaurant has a low rating because this place is Bomb af. My husband is not a fan of raw fish usually and he actually ate and enjoyed the Fontana roll so much. The service was fast and professional. They have generous servings as well. The wasabi actually had a nice kick to it unlike some other places and the nigiri I ordered was good quality fish. I like the serving size of the nigiri. It was a Perfect bite size. The miso soup was also very tasty and proper. I am just passing through but I will definitely be eating here again next time I'm in Fontana. Thank you Koya Sushi for a great meal! read more

Koya Sushi - Fontana roll & B sushi - Japanese Near Me - Fontana, California

Koya is a small restaurant with excellent service. The area can get busy since it shares a parking lot with several other businesses, but don't let that discourage you from visiting. The restaurant is clean and well-maintained, and the staff is fast, friendly, and polite. Out of the rolls I tried, the Lemon Love Roll was easily my favorite. It was perfectly prepared, and the combination of salmon and lemon worked incredibly well together. The flavors were fresh, balanced, and memorable. I highly recommend giving this roll a try! I also had the Lobster Roll and the Jalapeño Roll. While both were good, they didn't quite measure up to the Lemon Love Roll. That said, I really enjoyed the Jalapeño Roll and would definitely order it again. Overall, Koya offers great food, excellent service, and a welcoming atmosphere. I'll definitely be back. read more

We're back babyyyy! Was an absolute wreck when Koya shut down especially since sushi was supposed to be my after birth meal after having my son. Was sooo happy when I saw the signs off Sierra, nearly got in a wreck because I gasped so loud & scared the sh*t out of my husband. Finally placed a pick up order the other day & as usual, they did not disappoint. We ordered tempura udon, Philly hand roll, yellowtail cut roll, D4. which is a Superman roll, golden tiger roll & miso soup, and a teriyaki chicken bento. All of this for about $60. The food still as delicious as before and definitely hit the spot! Didn't get a chance to take a pic of the food because I was too excited but will be back again very soon! read more

I used to come here when I wanted a quick fix because it was close to my home and the cheapest. I was never crazy about the place but it got my cravings out the way... I saw it was open again on yelp and today when I called it was $30 for AYCE for lunch. I came gave it ankther shot since its been closed I thought maybe it got better just try again... NO the first thing (shrimp boats) come out within 2 min of ordering and was cold as if it was sitting there for someone else and didn't want to waste food. Then I asked for extra wasabi and only wasabi the guy gave my the smallest amount (I eat a lot of it and ask ahead to avoid bugging for more). My food kept getting mixed up either didn't come out or came out 2x and rounds Were mixed up. My calamari came out and my baked salmon roll both quickly as well and also cold. To top it the nigiri was mostly rice. I tried, but wont be coming back. read more

KOYA IS BACKKKKK! So delicious, how I missed literally the only sushi spot in Fontana. We were serviced by Danny and Maria, they were so sweet and took great care of us. Can't wait to have my date nights here again. They also redid the floors and the booths so everything looks great! read more

I have been coming to Koya for about 10 years now and I am always extending satisfied. The food is amazing and the ambiance is so relaxing. The waitresses are always a hit and a miss, as they get really busy and sometimes it shows that they're frustrated. However, it's never a horrible or even bad experience. They always push through and the men are always so gracious. Koya is truly a gem in Fontana. read more

Sushi nice and fresh. We love the Yummy rolls and spicy scallops and love the sushi. Love the service.

Koya Sushi in Fontana is horribly disgusting. The fish was warm and not fresh at all I went to this place because I was working in Fontana that day - Boy do I freaking regret it. I want you people who read my post to save your stomachs and wallets - it's really gross and if you do end up going here - just remember "I told you so" My friend and I tried "The All You Can Eat"- and it was more like "The All You CAN"T Eat" They even charged us an extra $5 buck for not eating poorly made sushi" When I tried to explain to the waitress that the food wasn't fresh - she said I just work here - Lol read more

I ordered food tonight. 5 rolls, miso soup, and salmon sashimi. My food was frozen!!!! $102 worth of food that I couldn't eat. All the salmon was frozen on all the rolls and sashimi. The soup was cold. I called and the guy on the phone gaslight me and told me it wasn't frozen and then said he'd check and then said oh ya it was frozen and said sorry but I can't re fund you your money. Awful customer service, hung up on me 3 times because I asked for a refund. Do NOT eat here. Save your money an go else where. read more

Awesome sushi spot. Found this place on accident the night before Thanksgiving and have been a couple times since. Still haven't been disappointed! The staff are great people and the fish is fresh and flavorful. Great portions and excellent pricing. My ONLY complaint, no squid. I love me some squid and they don't have it. But it's okay, the rest of their fish is great. See y'all again soon, keep up the good work. read more
