Navigli is a trendy bar and restaurant area along the old canals near Porto Genova. Here you will find many cafes and restaurants, antique shops, hotels and great gelato. I had lunch at the Osteria Al Coniglio Blanco (white rabbit) along the canal at Alzaia Naviglio Grande 12. It is a popular spot with the local business people nearby. There are numerous other cafes to choose from.
I also checked out the Maison Borella, a four star hotel down the street at Alzaia Naviglio Grande 8. It is a lovely small boutique property.
