SEARSPORT, Maine — Inside the new Homeport Tavern last week, it was a blur of activity as the owners got ready for opening night on Friday, June 17. With vendors dropping by and a dining room still under renovation, there was a lot to do. But the baby grand piano was already in place and a pot of gumbo was simmering on the stove — which both seemed to fit with the focus on hospitality and good food that owners Arnaud Lessard, Allison Lessard and Kip Dixon have in mind for the restaurant.
