I have so many adresses I would like to share with you, but I would first like to draw your attention on my favorite Italian restaurant in Brussels: La Gazzetta.
La Gazzetta serves the best burrata I know in Brussels and its daily pasta dish is to die for! Initially a wine bar, they offer great wine to go with your dishes. The staff is mostly Italian which makes it even more typical.
If you have a sweet tooth as I do, I would definitely recommend their tiramisu, which reaches perfection!
