One of my safe spots in the Seacoast region. Everything I’ve tried here is delicious and I’ve never been ill after eating here.

Everything was great! We had a large party, which they were able to seat quickly and we all had food not long after order. I had the gluten free pizza, which impressed me and was not dry or crumbly at all. Very, very good!

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.

My favorite place to get coffee or a smoothie in the area! Love the music and the staff are always very friendly. Really great atmosphere and decor. The pumpkin dirty chai is a fall favorite, and they make a really nice matcha latte as well. I love their açaí bowls and all of the smoothies. They are allergy friendly and have vegan/vegetarian options. The gluten free bagel and wraps are really good. Highly recommend for a breakfast or lunch spot.
