NYNM, It has been several years since I lived in Belgium. There are a bunch of good restaurants there, in Brussels the classic restaurant is "Comme Chez Soi". While you’re in Brugges please see the Madonna by Michelangelo. She is beautiful. She will hypnotize you.
As far as restaurants go…….there are many. Enjoy the mussels, the french fries, the cheese, the chocolates, especially from Leonidas, get the praline’……I have carried many of then across the Atlantic!
And above all, have a Duvel or Chimay capsule bleu for me. Ah…..la Belgique. C’est un beau pays!
