According to the S.Pellegrino World's 50 Best Restaurants, Denmark's Noma is the world's best restaurant of 2011. It is certainly worth noting that this is Noma's second consecutive year to win the award. The Scandinavian restaurant is headed by chef René Redzepi. He focuses on Nordic cuisine.
Noma's food is not considered traditional but more of an interpretation of the Nordic cuisine, says in Wikipedia. Just how radical it is I do not know, but reading that dishes can include radishes in edible soil is certainly eye-catching.
I became more curious when I read that type of food is influenced by Molecular Gastronomy. I wonder what it's like to dine in the world's finest restaurant. I hope I can eat there at some point in my life.
