Seafood noodles are a popular dish in many Asian cuisines, particularly in Chinese, Japanese, and Thai cooking. A 'seafood noodle signboard' typically refers to a restaurant or food stall that specializes in serving this dish. These establishments are known for their visible signage, often adorned with images of seafood and noodles, to attract customers. The dish usually includes a variety of seafood, such as shrimp, squid, and scallops, served over noodles, often accompanied by a rich, flavorful broth.
