Phenomenal service! We made a reservation online a noted a fish allergy at our table. Our host and server both took the time to clarify the nature and severity of the allergy and were understanding. Our server Sydney was friendly and knowledgeable. The food was fantastic. Generous portion sizes for the share plates and everything was delicious. I would come back to New Hampshire just for this restaurant.

This is the best Japanese food I have ever had. All of the food came out hot and perfectly garnished and tasted amazing!! I highly recommend the Miso Eggplant, Spicy Crab Fried Rice, and Karaage! All of the meat was perfectly cooked and basically melts in your mouth. Even though the items are a bit pricey, they are more than worth it! The staff here is incredible as well! They are prompt, helpful, and courteous. Our waiter did excellent in recommending the best dishes on the menu! Even though it is attached to the hotel, this restaurant is open to anyone. It's very beautiful and organized on the inside and was an extremely pleasant atmosphere for a slow meal.

Nichinan was recommended to us by a friend, and although we arrived without knowing much about the restaurant or its menu, the meal was exceptional. Each dish was unique, thoughtfully prepared, and absolutely delicious. We couldn’t have been happier with the food, and our server was both pleasant and knowledgeable. We also enjoyed a mocktail that was excellent, and finished the meal by sharing a dessert, which was incredibly tasty. The ambience was pleasant, and while the restaurant is not inexpensive, at about $75 per person including tip, we felt it was well worth it. I highly recommend this restaurant.

The place is gorgeous and it feels like you discovered a secret little pocket of Portsmouth. Cocktails were delicious and bartender was fun to chat with. The food... just, yes. It was superb.. we had sushi, top notch. Presentation, freshness, and color were brilliant. We had a special appetizer...it was like a schnitzel and was amazing. The money spent felt worth while.

I came here for date night and left with a new favorite restaurant! I don't think I've seen okonomiyaki anywhere outside of Japan and yet here it was- along with a ton of other very unique, very tasty menu items. We wanted to order one of everything, it was hard to choose! Our favorites were the sashimi, the sake roll, and the okonomiyaki. The steamed buns and tonkatsu were also really good, I like that we could get a bunch of small plates to share. Definitely get dessert- it was incredible! The cocktails were also top notch. The service was excellent and prompt, and overall the vibes of the place were really nice, it was cozy but still elegant, I will definitely be back!
