About Nisi

Nisi, meaning island in Greek, is inspired by the culinary traditions of Greece. Our menu brings together small plates and full entrées built around fresh ingredients and classic Mediterranean flavors.

From dolmas and saganaki to salads, gyros, and seasonal plates, guests can share a few dishes or enjoy a plate of their own.

Located in Portsmouth’s West End, Nisi offers Greek hospitality in a setting designed for gathering.
