At night, the Navigli Distict is a great place be in Milan. Restaurants line the canal and people walk the streets to find their favorite hangout. The scene is hip, colorful and lively. This area is known for having some amazing antipasto deals. For around $12 you can get all the antipasto you can eat and a drink of choice. With some care you can get a pretty great, inexpensive meal out of it all! We really enjoyed ourselves there and would definitely revisit if we returned to Milan.
Fun fact: At one time Milan was filled with canals like Venice. However, unlike Venice, they were all man made. Almost all the canals were later buried because they became a breeding ground for disease.
