What to expect at a seafood restaurant
Seafood restaurants range from fish shacks and oyster bars to upscale dining rooms and Cajun boil houses. What is on the menu depends heavily on the region: lobster rolls and clam chowder in New England, crab cakes in Maryland, shrimp and grits and fried catfish in the South, crawfish in Louisiana and salmon and Dungeness crab in the Pacific Northwest.
What to order
- Oysters – ask where they come from; local varieties are usually the freshest
- Fish and chips or a fried basket – the casual classic
- Chowder or gumbo – regional soups and stews
- Seafood boil – shrimp, crab or crawfish with corn and potatoes
Good to know
- Check the “market price” before ordering lobster or crab.
- Coastal seafood restaurants get very busy on summer weekends.
- Raw shellfish carries extra risk for some diners; ask staff if you have concerns.
