Sushi Koyo

This was the best sushi bar I've ever been to. You won't want to go to another place, I guarantee it. The only thing you need to know is the chef will choose your meal for you but it's definitely worth it. I drive 30 miles away just for dinner. Try it for yourself, you won't be disappointed!! Pros: Excellent sushi more

After living in LA with its many sushi restaurants, I tried to find a local sushi restaurant that at least served okay sushi. I was more than happy with the atmosphere, service, and best of all, the quality of the delicious sushi here! Love the cozy atmosphere! Pros: Great food, service, and price Cons: Dining area is a bit small more

The food: Pros: Spicy Tuna Sushi Cons: Everything else more

I'm not too fond of sushi myself, but my husband loves it. So I was determined to find the best of the best. We've been to many sushi bars/resturants before, but this place was by far the best! Like I said, I don't like sushi, but Hiro (the chef) made me some sushi he knew I would truly love. The blue crab roll was the best. I suggest everyone who goes there order it. The whole thing just melts in your mouth with ever bite. The shrimp rolls are good too. With just a hint of wasabi spread under the shrimp and rice, it goes great dipped in soy sauce. Even the California rolls are different from your ordinary sushi bar. Hiro uses real crab meat. No immitations here. Top your meal off with a ice cold japanese beer and your set! Pros: Fast service, Friendly, Fresh meat Cons: Crowded on Friday more

Hey everyone, me and my wife were looking for the best and we found it. Forget all those other chain restaurants and all you can eat places, Hiro is the ""MASTA"" when it comes to sushi, providing you with nothing but the best cuts and the most tasty freshest oysters I have ever eaten......and that secret sauce of his, goes great with an ice cold brew. And something we never expected was his sense of humor ""HIRO HAD US ROLLING ON THE FLOOR"" this was the best dinner we have ever had. THIS IS OUR NEW SPOT FOR SUSHI,WE WILL NEVER LOOK ANYWHERE ELSE AGAIN. (you have to try the BLUE CRAB ROLL it's very delish!) and HIRO hooked me up with some salmon skin rolls that just made me want to keep eating, their toasty outer skin and that soft melt in your mouth meaty inside was just OUTSTANDING. Pros: fast service, very friendly, could'nt be fresher Cons: no reservations more

I have eaten sushi in many different restaurants and i have to say that this family owned restaurant has got to be the best. I have gotten to know the chef personally and found that he goes to the fish market to hand pick his own fish. I have been coming here for the past 10 years and have not found a better sushi restaurant yet. I highly recommend this restaurant if you want a traditional sushi restaurant to dine at. I personally recommend the butterfish and the blue crab hand roll. they are to die for. Pros: fun environment more

No other sushi chef knows as much as Mr.Takemoto. Every piece of fish was best ever. Highly recommend for a chance to enjoy real sushi on this side of the pond. Oishii sushi arigatougozaimashita. Gochisousama. Mata kimasu. Pros: Great Sushi, Great Sushi, Great Sushi more

Trust Chef Hiro. He's the only person behind the sushi counter. This wise cracking sushi chef is entertaining, and he knows how to serve good tasting sushi. This hidden gem serves the basics. No Rainbow rolls served here. With the quality of the sushi, you don't need those rolls. Pros: Sushi, Lunch Special, Chef Hiro more
