Remember the name of this neighborhood: Isola. Isola in Italian means island. The reason for this is that the area was originally isolated, closed off either by streams or by railways. Traditionally this is the working class area, and maybe for this reason this is where most of Milan associations are, from trade unions to environmentalist groups to city-bikers etc. This is also the area of the laboratories, the artisans shops, etc. It’s definitely worth a visit!
Odd enough, Isola is just behind C.so Como district, which is famous for its models, expensive cars and discos. Unfortunately Isola is undergoing a big renovation and it is getting more and more similar to C.so Como, full of charming restaurants and cafes with high prices and poor quality.
Les Folies is an exception to this trend: it looks like a normal bar with a side room full of small tables (sort of French bistro) and it has delicious food. The prices are quite good compared to the quality of the food and the way it is displayed on the table: I had prawns and rice and got it served in a circular shape on a black plate that made the white and pink stand out. I suggest you keep some space for ordering a cake at the end of the meal: taste and presentation are both outstanding.
Closing time depends on how many people show up, therefore it might close earlier.
