The term "seafood restaurant" refers to a type of dining establishment that specializes in serving seafood, which is any kind of food derived from the ocean such as fish, shellfish, and other marine life. These types of restaurants typically offer a variety of fresh seafood dishes prepared in different ways including grilled, baked, fried or sautéed, among others. They may also serve non-seafood items on their menu but are primarily known for their seafood offerings. Seafood restaurants can range from casual to upscale and often feature waterfront views or a nautical theme in their decor.
