A St. John River Valley beacon since 1945, Rock's is Fort Kent's go-to place for three meals a day. Take-out is very popular; if you plan to eat here, service is eat-in-the-rough. Walk in, study the wall menu, place your order and pay. Then find a seat at table or booth or one of the communal counters. In a short while, out comes a member of the staff with your cheeseburger, chili dog, sandwich or hot-lunch plate.
