Bento comes with CA rolls, miso, and salad with your choice of proteins. I got the salmon teriyaki which was pretty solid. For $11.95, this spot is legit. Service was friendly, and inside was spacious and clean. Parking is both street side and behind the building (they have a separate back entrance).

Hi friends, we had an absolutely amazing experience tonight for Valentine's Day. The customer service was excellent with personal experiences, always making sure we had our waters filled, and our appetizers out. While they were really busy because of the holiday so our entree food wait times were a bit of a wait, so they filled the room with so much love and great times by drawing our table number from a box, coming over to us and allowing us all to pick a number from the box and whatever number we picked we got a fun beautiful gift! we got a glass dome with roses that light up! it will be beautiful to add to our table. they also gave us complimentary edamame. On top of when we got our food, the food was great. Koyomi and the employees made our Valentine's Day absolutely great with the family and we couldn't express better words! 10/10 night with our family and we hope they had a good night as well despite being very busy. thank you koyomi for an amazing experience! friends, please stop here, foods great, service is great and you'll leave happy

Solid sushi restaurant. We came here on a random weeknight and we were one of the last customers. Service was quick. Spacious inside. We ordered a bento box with salmon and tempura. It was flavored well, I really enjoyed the salmon, not fishy at all. The tempura batter was perfect, nice and crispy, although I wish they had onion tempura in the mix. We also ordered the November roll and the lion king roll. Both were delicious but the November roll was huge! Plenty of fresh sushi, we really liked it. We would like to come back and try other items on the menu. There is street parking and there's also parking in the back.

I have always driven past this place but have never actually ate here until recently. I came at lunch time and the restaurant wasn't very packed, the waitress could have been more attentive. My lion king roll was for sure a 10/10, it was so good! I also got the edamame, it was okay i thought it was going to come with garlic but it was only plain edamame with a side of soy sauce. The restaurant was clean, there is a parking lot throughout the back side of the restaurant. overall this is a pretty good sushi place.

Our group of 7 came here for an early Sunday dinner. There's a small parking lot in the back but it was full so we parked on the street about a block away. We called ahead for a table and it was already set when we arrived. Koyomi is a spacious restaurant with a warm welcoming ambience. The servers were really nice and helpful. They have an extensive menu. Most of the group ordered variations of combination dinner. We had baked mussels and cold tofu with ponzu sauce for appetizers. The cold tofu with ponzu sauce was beautifully presented. There were 10 pieces of tofu drizzled with ponzu sauce and topped with green sprouts. One order was sufficient for our group. The baked mussels had only 4 pieces per order, however, so we had to order two. The price for one order for 4 pieces seemed high to me. I find that some items on the menu were good value, while others are pricey due to the small portions. The nigiri sushi set I had was of particularly good value. I had 10 nigiri sushi pieces that were fresh and delicious with different variety of good quality seafood. It came nicely presented on a long rectangular wooden tray. I was expecting a higher price for this entree, but it was very reasonable. The group enjoyed their combination meals which included miso soup and a nice salad with delicious citrus dressing. The portions looked small, however, as the foods such as soba noodle, tuna sashimi, etc came in small square wooden boxes. Service throughout was great. Our ice waters were refilled many times, and the server was friendly when we asked about a particular dish. Overall we would come back again for the fresh sushi and explore the menu some more.

3.5 for me. We got takeout and ordered two rolls. I didn't get a chance to interact with staff since my friend was the one that picked up the order. Here's my review on the rolls. Great prices. Double Salmon - The reason why I order this was because the menu states salmon and lemon. I believe it was drizzled with sauce too which overpowered the lemon taste. I didn't get the impression of a fresh salmon roll for this one. Maybe it was the sauce mixed with the dragon roll because both of the rolls came together in one box. (?) Dragon - Spectacular! It is filled with crab meat and shrimp tempera inside topped with avocado, eel, and eel sauce. Perfect balance of sweetness and crunchiness making you want to devourer the rest of the rolls.

Busy spot! Hectic service, but boy were they trying their best. Rolls were clean tasting and well put together. The Raider roll especially had a lovely buttery finish. My wife enjoyed her sashimi, which was fresh and smooth. Highly recommend!

I got a chirashi bowl and it was super fresh and yummy! It came with hamachi, sake, maguro, tai, albacore, and mackerel. My friend for a dinner combo with tempura and chicken katsu which was solid. Service is very quick. The restaurant is roomy with lots of tables. Good amount of parking in the back.
