Simply The Best – Iwayama Sushi is simply the best. You get top notch food in a relaxed atmospere. There is something for everyone from burgers to sushi, to hawaiian plate lunches. They fly in fish several times a week from Hawaii and boy is it good. The previous commentor does not know anything about Iwayama Sushi. We go once a week as most of their customers do. Its that good.

Days-old fish, Tiny Tasteless Tempura, Clumpy Rice – My sister and I were both completely unsatisfied by everything about this restaurant, and we would NEVER come back here. We like to support small businesses, especially those in and around our neighborhood. However, this restaurant is a true disappointment. The sashimi was of bad quality. What I mean: The salmon tasted as though it was at least three days old. The tempura batter was oily, dark, flat, not like the crispy and fluffy kind one would expect of tempura. The seared tuna was pre-seared. At other establisments, the fresh tuna would be seared once the order is placed. This place had the pre-seared tuna in the sushi counter. The prices seemed high considering that the tempura pieces were very small. At other restaurants, the tempura would be wide (2 fingerwidths), but at Iwayama, the tempura shrimp were long and skinny (1 fingerwidth). They even messed up the rice that came with the meal! The sauce that came with the tempura (my personal favorite part) was oily and bland. The Japanese rice is supposed to be short grain and sticky when cooked. The rice at Iwayama was clumpy! The tempura vegetables were even worse; the string bean had a black spot on it (ie, not fresh ingredients). If you want to eat real sushi or even decent food, I would NOT recommend Iwayama Sushi. They did have a decent California Roll (2 for $5.50) -- typical price at other places. The Unagi hand-roll was not done correctly (the bottom of it was not closed completely. It wasn't a cone. It was more like a funnel, where there is a hole on the bottom of the hand roll.) The unagi did not have the crispy outside. It was a mushy piece of eel. The happy hour is 'okay'. It lasts one hour and one hour only. 430 pm to 530 pm. There's a lack of decor. The 'art' on the walls were 2 white eraseboards announching the specials. The kitchen/sushi prep area just looked smudgy/not clean. The 2 chefs behind the sushi counter were Hispanic. Hey- I don't care what race you are, as long as the sushi is good. Well...the sushi ISN'T good. I really was hoping to find a good sushi place around this area, but Iwayama is definitely not it. Sushi Fontana (Cross St and Wadsworth) has a better atmosphere and fresher fish. Sushi King (c470 and bowles) has better selection and better tempura. I usually would not write this much for some review online, but we both felt so strongly about this dining experience.


Yes - I eat sushi at a lot of places.

No - I don't work for another restaurant that's trying to sabotage this place.

If you are the owner/associated with this restaurant, and you would like me to re-visit this place, feel free to contact me. I will be glad to provide details and feedback. Thanks for reading.

Best Sushi in Denver – As a seasoned traveler and sushi fan from "back east" I have had my share of sushi samplings.

I tried the other big names in town, and while some where respectable, they were also quite expensive.

Then on my last visit in early April I found Lee, The Big Kahuna. Lee is warm and friendly and makes KILLER sushi.

I loved it so much I went two days in a row. I recommend sitting at the bar and talking with Lee. He will ask what you like and make something special for you.

What is also nice is when he sends samples of his creations over the bar to you at his pleasure. Now this is truly good service with a smile.

Thanks Lee and see you next time I am in Denver.
