We checked out the Tennis Halle last night. No, not to have a game. The indoor tennis centre has a restaurant attached and diners can watch the energetic play a few sets, while they tuck into their food and wine.
I couldn't be bothered cooking last night, so we wandered up for some pizza.
From the outside the Tennis Halle looks for all money like an old aircraft hangar. Take it from me, the interior is much more interesting.
