What is the most popular appetizer and where is it sourced from?

The most popular appetizer in this context refers specifically to mussels sourced from Prince Edward Island (PEI). PEI is renowned for its high-quality mussels due to the ideal growing conditions in its coastal waters, leading to a firm texture and rich flavor that are highly sought after in culinary circles. This region's musseling techniques and the clean waters contribute to both the sustainability and the premium quality of the mussels, making them a favorite for many restaurants and seafood enthusiasts.

While other appetizers like calamari, shrimp, and fries certainly have their own merits and regional significance, the specific acclaim associated with mussels from PEI underscores their status as a favored choice in appetizer menus, particularly in seafood dining.
