For more than 60 years, the Original Waterfront Crab Shack has peppered its patrons’ palates with steamed, grilled, and fried seafood, as well as juicy burgers and crisp salads. As chefs bustle in the kitchen, libation wizards behind two full-service bars dole out wine, beer, and liquor. Overlooking the Santa Rosa Sound, the eatery’s expansive outdoor deck boasts picnic-table-style eating and ample views of a trolling boats and the occasional waterskiing muskie.
