The lovely city of Bruges is surrounded by canals. It's beautiful, but touristy. This is where you get mussles and frites, as it is pretty close to the ocean.
Crispy, hot, frites! Dipped in aioli and in your moules.
Moules! So good. So good with beer. More than once I found extra sea creatures in my moules- once it was a teeny baby crab, and another the world's smallest scallop. Extra creatures!
