  • I recently had the pleasure of dining at this incredible sushi restaurant, and I must say, it was an exquisite experience from start to finish. The sushi itself was a work of art. Each piece was meticulously crafted, showcasing the freshest ingredients and an impeccable attention to detail. The staff was exceptionally attentive and knowledgeable, providing recommendations and ensuring our every need was met.

  • Amazing food and service!!! My friend and I were completely satisfied. Not only the food was so fresh and delicious, but the happy hour menu prices were unbelievable!!! They are BEST deals for Japanese food. We are going back again soon. This place is highly recommended to everyone who hasn't tried yet!

  • We were a party of 10 and didn't have a reservation, but they accommodated us right away and got seated at a semi-private area quickly. Very friendly staff. Wide variety of dishes. Reasonable prices. They also have 2 sets of happy hour menu that has good selection. Will definitely be back!

  • I ordered the beef sukiyaki and two sushi rolls. Sushi was great! I got spicy salmon and spicy scallop because the hostess suggested I get it. The side salad was great! Amazing dressing and so refreshing along with the miso soup. My main course is always my go to when I come here. The sukiyaki is so flavorful and fresh. Definitely would recommend this place
