This is my favorite place to come to! Best sushi ever. The chefs are so friendly. The staff is so friendly. Shout out to their staff and food!

Wow! The fish is so fresh here, especially the red snapper. So Incredible. Many veggie options as well and so many roll types that I have never seen before. Onsen definitely has a unique style and flavour. The portion sizes are also so good Every staff member is also so friendly, when leaving, everyone said thank you and goodbye as we left. I really love this restaurant

This place is AMAZING. My husband and I came here with our newborn on New Years Eve for an early-ish dinner! The place was buzzing with people. It was very busy and still the service was fantastic and the food was amazing. The staff was so nice and friendly. The amount of food being pumped out by the sushi chefs was incredible to watch. The sushi was delicious and so was my husbands chicken/rice entree. This will definitely be our only sushi spot from now on! Our newborn slept the two hours we were there! Mom was scared he was going to wake up screaming but our server got us the bill fast and got us out of there!

Party of 11. Great job accommodating everyone. The last dish was as perfect as the first. Kudos to the chef and service. Good job.

I often stop in for lunch, eat by myself, and read. It's quiet with decent music, I do not feel out of place sitting alone. The staff is lovely. The food is great. The prices are very reasonable. I highly recommend.

The owner Jason is an absolute amazing chef. Everything that comes from this restaurant is top quality and delicious. Our server, Ken, knows us well and is very kind and accommodating. The fantasy roll is one of our favorites, but every roll was so amazing that we could not pick a true favorite. The spicy tuna and avocado bowl was astounding. One of the best sushi restaurants on Long Island without a doubt!! Recommended to all sushi lovers!

Tasty appetizers, excellent quality sushi and choices of specialty rolls. Real friendly staff!!

Okay two words, BLOWN AWAY. I have never, NEVER had a spicy tuna roll as good as I did from Onsen tonight. AND I got it to go. I'm so hyped to come back with my boyfriend and have a nice sit down dinner. It looks adorable inside, i was very hungry and didn't snap a pic, sorry. I also got a mango shrimp roll which was very tasty and the shrimp tempura! It was all so delicious. Best part, they also gave me a banana? No clue why or how it got there but hey it's a great source of potassium! I'm honestly so excited to go back and bring my boyfriend and enjoy a nice meal. Also the lunch specials seems pretty solid...
