This is a fantastic little sushi joint in Littleton; by far our favorite. We regularly order takeaway as this place is very popular (although I believe that they don't do takeaway on Fridays). Definitely worth a visit if you are looking for a fun, delicious spot in Littleton.

I visited with friends. It was amazing to find Hawaiian food in Colorado, with yummy sushi & Asian food as well! My favorite was Steamed Shiromi, with ginger! Tip - be sure & get all your orders in at least 1/2 hour before they close. I was going to place an order to go, but waited too long.

Been going to this place for almost 2 years now. They just had a management change but don't you worry. The food still taste as good as before. Don't pass up on the coconut cake.

We bring our family here at least once a month. The sushi is great, with a large selection to choose from. The Hawaiian food options are incredible, Moco Loco, the Santiago burger etc are perfect! Definitely a family favorite that is tucked away in a strip mall, so it feels like you and the other customers are all in a... More

Tucked away behind a gas station is an unexpected sushi restaurant that serves Hawaiian food. For your don't do sushi friends, there is a Juicy Lucy cheeseburger and more. How fun is that when you're craving sushi. It gets crowded around 6:30pm in this small casual neighborhood. So yummy sushi for dinner followed by Hawaiian malasadas for dessert, yum.

I went to the Iwayama Sushi and Da Big Kahuna Bistro with my son and his wife. The restaurant is unassuming and is located in a strip mall on the corner of Simms and W. Brandt in Littleton. The sign in front only says "Sushi". The restaurant is small, but popular. Upon entering, we were greeted by one of the... More

My sister and family are regulars at this place--and they are foodies to an extreme. We tend to go here every visit we make to Colorado and there's usually a special occasion involved (e.g., birthday, graduation, etc.). That said, it's a very small place, so go early if you're with a crowd. Concerning food, I struggle to chose because everything... More

My eighth grader is a big Spam fan, (thank you, Mr. Andrews of Goddard Middle School). When I mentioned that I had noticed that we had a Hawaiian option nearby, she couldn't wait to get there. They actually only have one Spam item, and it's "Sushi", which is probably a good endorsement for them but leaves out so many Hawaiian... More

But my wife is. This is where I was introduced to sushi, and I have never regretted it. Of course, when you start with one of the best, everything else misses the mark. Teriyaki chicken is great. The teriyaki beef is the best thing on the menu in my opinion. Made fresh everytime. Moderately priced..downside is they have Japanese portions,... More

After having a friend recommend this restaurant many times, I finally tried it. What can I say, Iwayama is now my Families favorite restaurant. This last month I think we ate there at least once a week. The food is amazing, fresh and handled with care. This restaurant is family owned and they take great pride in serving top quality... More
