Opened in 1891 as one of 14 market halls built to supply Berlin with fresh groceries, this architectural gem has survived the war and then almost fell victim to dumping-price shops. A citizens' organisation recently decided to take over and it's slowly becoming THE place to go for conscious and fresh shopping.
Apart from being interesting to look at, the hallway to the toilet is lined with a comprehensive history of the market hall. Furthermore, there's a street kitchen and cafe open every day from 12:00 to 16:00.
Check out Street Food Thursday as well as their calender: They often have special events in the weekends, usually around organic/fair trade shopping.
