★★☆☆☆ 2.0 zoe g · Feb 2026

The waitress was awesome here!! However, the water tasted like chlorine, so we got sparkling instead, which ended up being $20 extra on our bill for the four of us. We came for lunch, which was a limited menu unfortunately, and split the spanakopita (very small serving), gyro flatbread (had fries on it, which was kinda weird) fig flatbread, saganaki (which was probably my favourite...fried cheese with fig jam), and rice pilaf. Every dish had feta lol. The food took a very long time to come out, although it was not very busy when we went around 1pm. The plates they used were very aesthetic, and the overall vibe was very...white.

After a long absence, it is nice to have Greek cuisine back in Portsmouth. This eatery just opened. It is not yet doing online/ takeout orders. The staff was amazing. Patience is necessary as the the seating capacity is small and you may have to wait. Already there are a lot of repeat customers

★★★★★ 5.0 Melani Taillon · Jan 2026

The space is absolutely beautiful and welcoming. The staff is super friendly and knowledgeable AND the food is incredible. As someone who is gluten free, I was thrilled to learn the fryer is 100% dedicated gluten free. The lemon chicken, superb and the zucchini chips, I’m still dreaming about. I'll be back for sure.

★★★★★ 5.0 Anna Salisbury · Feb 2026

The food was amazing and most of the menu is naturally GF. All that is pictured is GF. They also have a dedicated GF fryer which was amazing and hard to find as a celiac. The decor was very cute and on theme with cliche Greece! Our server was pleasant.

I heard there was a new Greek restaurant in Portsmouth and had to try it! Nisi is small and cute inside, with simple, authentic colors and decorations like you would find in Greece. When I arrived, the host stand was empty. A couple servers walked by but did not acknowledge me or the people that came in behind me. There is not a sign indicating to wait, so a "we'll be right there" or "seat yourselves" from the servers would have been helpful. After a couple minutes, I walked up to the bar and was greeted by the bartender. She said it was ok that I sat there, then grabbed me some water and a menu. I cant remember her name but she was friendly and her service impeccable. Her service deserved 5 stars. I gave 4 stars for service only because of the start of my visit but the rest of it w
