At Coastal Blue Oceanside Bar & Grill, table-side chatter is accompanied with the distant shimmering of the ocean. But here, no sense is more grateful to the ocean than taste. That's because Coastal Blue serves some of the freshest seafood in Diamond Beach, including signature jumbo lump crab cakes and warm, buttery lobster served on a New England split roll. Bright, open-air dining spaces add additional layers of elegance, highlighted by an island-style trellis dotted with white umbrellas.
