My friends and I had a lovely visit to your restaurant a few days ago. A couple of our friends are celiac, so picking a place that can deliver despite dietary variations is key. Your server, Dean helped us through ever step of our visit. Not only were the drinks and food above our expectations, but the service exceeded that. Dean answered all our allergy related questions and gave us a sense of confidence in your brand. We enjoyed our time at your restaurant and cannot wait to return. Thank you very much Dean and staff. Best, Amelia
The Kitchen
Accommodating
171 Islington St, Portsmouth, NH 03801, USA
Charming spot with a cozy vibe, a lovely side patio, and must-try spudsters that steal the show—perfect for casual dining and great drinks!
A cozy local restaurant that offers their unique take on classic American cuisine. They are located in a charming building with plenty of street parking available surrounding the establishment. For nicer weather, there is a side patio with tables shaded with umbrellas and their main dining area. The selection of food is perfect for lunch or dinner and not overwhelming, plus they have a full bar. They serve plenty of local beer and cider, which is an excellent way to sample what the area has to offer. The majority of the menu is gluten-free, and they do offer gluten-free substitutions for sandwiches and pasta. The real highlight of the meal are their spudsters - mashed potatoes made into little conical shapes with a piping bag, probably frozen, and then deep fried. They have seasonings and sauces to choose from to create endless tasting combinations. Absolutely my new favorite appetizer, and I would come back just for these. Everyone enjoyed their lunch and we were very happy we decided to stop. We will definitely be by again when in the area.
