Solid four stars for their sushi/sashimi for 1. Had it delivered and it was super fresh and delicious. I do wish that there was more nigiri (5) and a better selection of fish but still very solid. The tuna roll had a great fish to rice ratio. I was very happy.

Local Sushi restaurant that has been in town for more than 25 years. Excellent food highly recommend

The food was authentic Japanese. Everything was so good. The owner came out to chat with us and he had some experience in the restaurant business. The sushi was so fresh and the service was on point. Everything was so well made and you could tell it was Japanese made sushi. Will become a favorite.

Amidst a sea of so-called "Asian Fusion" eateries recently opened in the area, Koiso's authentic Japanese food and ownership really stand out. Family owned for many years with yummy food, homey decor and comfy seating. Today we had lunch at Koiso after a several year hiatus, and found that their service and food are even better than before. The lunch set, a bargain at $19.95, gives diners a choice of four sushi entrees, a small salad with fresh ginger dressing, plus a full size bowl of tanuki udon. The udon was so delicious with its slightly sweet broth, tempura flakes and plump noodles. We both chose the five piece nigiri sushi as entree course, every piece was fresh and tender. We were hungry so ordered a couple of extra appetizers too. Koiso's version of age dashi tofu was among the best I've ever had, lightly fried with a thin coating nestled in a tasty broth and topped with chopped green onions. Excellent shumai dumplings were made with savory shrimp filling encased in delicate dough. For Yelpers who may have had a so so experience at Koiso in the past, please give them another try for improved "omotenashi" service and yummy family style Japanese cuisine. Free street parking in front as well as a small lot in the back. I can't wait to return and try their other sushi and cooked dishes!

I take out sushi a lot and this was one of the best spots. I will be taking out from here again and would love to dine in as the inside looks cute and cozy with the traditional Japanese sit on floor seiza. The sushi rolls were fresh and delicious. The only downside side was the rock shrimp was soggy and not crispy. The food was made quick and the service is friendly.

Ordered a huge takeout order here online. They were so friendly when I picked up and the food was fresh and delicious! Lunch special was reasonably priced and no items were missing! Pleasantly smooth experience and I'd definitely come back to dine in. The soy sauce was a bit salty though.

Very good, could be a place that we visit, currently we simply have not found a place for sushi et al that hits all the notes. I walked into a completely empty restaurant at around 5:45pm on a Friday, asked "do you have a reservation?" no, I reply, do I need one ? lol Soon, a few more tables join me & the room is filled with conversation & some warmth. In the mood for some rolls, I order the combo that offers Miso soup, which is excellent. The rolls, they are ok, good..not too much rice, but I must have missed the memo that rolls are now 6 pieces, since the mid 1980's what had been 8. Also, a Mango Kani Salad, some crunch on top. Very good, a bit too much dressing, but a good portion that leaves me with 1/2 for tomorrow. If you read this & live nearby, do you have a favorite local Japanese spot that makes great sushi & sashimi ? The reviews on Yelp always seem to be loved, with many 4-5 star reviews, but when i search them "most recent first" there is a sudden drop to 1-3 stars with an explanation "new owners, used to be amazing" etc. Pleasant service, tables for 2 very close together, a few tatami tables and 2-3 tables for four to six people. I'll return soon & see if the positive feelings remain.

Nakamori-san is a wonderful host. The food was fresh and in the service is in the true Japanese family-style spirit! ITEDAKImasu
