Thanks to Kelly for emailing this recommendation:
My husband is vegan and I am dairy free. We both LOVE going to Hermanos Cocina in Concord, NH. They are a Mexican restaurant and make most of their ingredients daily. They have a full page of vegan food and all condiments with a dairy free option (aka- dairy free sour cream) so you have the full experience.
