I was just there on Friday and it was amazing how unfinished things are. Panels missing, no seating near some gates.
It’s a very nice mall that happens to have airplane gates.
Really though, the airport’s homepage sells it the best.

> Shopping Therapy at Berlin Airport Both Terminals 1 and 5 (Terminal 2 is not operational yet) offer a “shopping heaven”, large shopping areas where you can find whatever you may look for. Last-minute presents, famous brands, local stores, BER airport has all the answers depending on your desires! Are you travelling on a budget and want to avoid unnecessary expenses? Take a walk and go for window shopping. Still a pleasing and relaxing experience!
Have you been there? It’s a bit of a weird ghost-town. Definitely not quite in ‘full service.’
