Around Europe in many dishes 8: More North Welsh delights

Lovely day meandering around the lanes and byways of Anglesey and Holy Island, on the ancient-history trail, looking for ancient settlements, from the Neolithic to the Romano-British, scattered throughout this amazing bit of North Wales.
And found some nice food too!
A lovely simple lunch of fresh pea and mint soup, with crusty bread, in a little cafe along the way: deliciously flavoursome and satisfying yet so simple!
Dinner in Beamaris seafood place rather more sophisticated but still with that special delicious simplicity of good ingredients: local Menai Strait mussels in a garlic broth; and fish pie bursting with haddock, salmon, cod, and prawns, with in a creamy leek sauce, under a crusty golden cheese top!
