It's an indoor market, which makes it a great option in winter if you are looking for anything from kitsch to classy. I like it because you find lots of old objects that transport you to the past.

Located in a vintage ballroom, Clärchens Ballhaus is a nice lunch destination. Try the "Käsespätzle" with applesauce!

Volksbühne hosts and produces an intriguing program of theatre performances, contemporary dance and concerts. 

A cute Swedish style breakfast/ cafe place owned by really nice friends, they have a cinnamon bun to coo over, its so sweet and yummy :)

A place where I spend some time almost everyday is the Marheineke Markthalle on Bergmannstraße in Kreuzberg. It's just around the corner from where I live and a great place to buy fresh food and products from local farmers or all kinds of delicatessen from different countries. Many market stalls also sell freshly prepared food and it's always busy at lunchtime. For saturday mornings try the original french croissants.
