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.

They understand allergies and cross contamination, they are known for their high standards of allergy friendly food. My group that went had lots of different allergies and they were able to make safe food for all of us. I got an amazing gluten free and dairy free meal. The staff was very respectful as well

I have celiac disease, and the minute the server (whose name is also Monica) found out she was very diligent in making sure my food was safe! She double checked each dish so that I had no worries about eating :)

We eat at a lot of poke places as many have gluten free options for my daughter with celiac disease. Not the best poke bowl we've ever had. It was okay/good. A decent option when there aren't that many choices available.
