I am a Belgian and I love "moules frites" with a good beer. Restaurant "Chez Léon" is an institution in Brussels. It opened as a simple café in 1883 in "rue des Bouchez", the historical center of Brussels, near the "Grand Place". The funny thing is that the mussels in any belgian "moule frites" are not belgian but come from Zeeland, part of The Netherlands ! And to enjoy the great taste of these mussels (they just arrived in the market - in Belgium, it becomes a commercially evenement just like new beaujolais in France), no funny garlic sauce : just mussels, celeri, onions and carots to get "moules marinières".
