at the Water's Edge
We are now closed for the season.
Getting here is a breeze and part of the fun. Whether you take a short ferry ride from Portland's Old Port District or come by private boat, it's a pleasure to glide across the sparkling waters of Casco Bay and take in the remarkable scenery that surrounds you. When you disembark at the ferry terminal or marina, you'll find it's only a few steps to the restaurant, where a warm welcome awaits.
