Fancy a game of table tennis? Well, you’re in good company as Ping Pong is by far the most (and totally unofficial) popular sport in Berlin. They even created the International Table Tennis Foundation in 1926 to host European Championships. In summer you can’t miss the peeps playing at the public tables strewn about the city... but don’t worry if you didn’t pack your paddle, lots of stores cater to these Ping Pong-mad residents and sell them for just one Euro. Grab one and get in the game! It’s the perfect way to mix with the locals or meet that special ‘vacation’ someone.
