The Market Chef is located one block from the ferry terminal in Friday Harbor. They have a broad selection of made to order sandwiches that are consistently excellent. Their bread is always freshed baked that morning.
Their fresh case offers a variety of prepared salads and main courses available to eat in or take home. These items often represent what is freshly available on the local farms.
My only complaint is that they are closed on weekends.
If you have having an event on island, they also do catering.
