When restauranteurs like Gordon Hamersley, Barbara Lynch, or Frank McClelland order fish, they call Kim Marden’s wholesale operation. But the pros aren’t the only ones Marden’s supplies. Amateur cooks can also get the and freshest fish by heading west to Marden’s Wellesley retail shop for a dizzying selection of grilled wonders and shelled delicacies. Squamish about cooking fish? In the adjacent restaurant, there’s a vast selection of fresh and frozen appetizers and entrées, and soups and sandwiches made to order. The stuffed lobster rules.
