Welcome to Nisi

Rooted in Portsmouth, New Hampshire

Nisi—meaning island in Greek—is a small escape from the everyday. Inspired by the culinary traditions of Greece, we bring people together through fresh, seasonal ingredients, bold Mediterranean flavors, and warm hospitality in Portsmouth, New Hampshire.

From hand-rolled dolmas and crispy saganaki to vibrant salads, classic gyros, and thoughtfully prepared entrées, our menu moves easily between dishes meant to be shared and plates meant to be enjoyed on their own.

Proud to join the Portsmouth dining community, Nisi offers Greek hospitality, bold flavors, and a welcoming table to the neighborhood, whether you’re here for a casual dinner, a long meal with friends, or a quiet night out.
