Slider's Seaside Grill sits on the south end of the island at American Beach, where the road runs along the dune line and the Atlantic is close enough to hear. It is a casual, order-at-the-counter kind of place with an outdoor deck, fresh shrimp and fish, and the kind of straightforward cooking that suits a beach lunch: shrimp baskets, fish tacos, grouper sandwiches, cold beer. Nothing complicated, nothing bad.
The location away from Fernandina Beach means it draws more locals and fewer tourists from the resort hotels at the island's mid-section. The deck faces east, which makes it an obvious choice for watching the ocean while you eat. The portions are generous and prices are reasonable by island standards.
