The Zoo is a good day out as well. Absolutely huge and you can do 5-6 hours just going round once with the odd stop for a beer at the cafe.
We went and during the afternoon they started setting up little stalls on the main entrance path. Didn't know what it was but started noticing people walking round with little snacks and drinks so figured it was some kind of private function and thought no more of it. Come 6pm they start turning off the lights and it's time to go and we head to the exit and go past all these stalls. They're really busy and everyone is grabbing food and drink and I ask the missus if she can see any money changing hands?
We end up convincing ourselves it's some kind of free thankyou thing from the zoo and we just happened to have dropped on so she grabs a couple of small bottles of wine and I grab some food and we go at it. More wine and find a table and all is well in the world. After a bit I clock the beer stall and decide to have a change from the wine. I wander over to the beer stall and there's just a single beer left as a bloke's grabbed a couple just as I get there. I point at the beer, smile and ask the girl "OK?" and she says "Ja", I say "Danke" and then asks me something in German.
"Sorry, English..."
"OK - you want two beers, I pour another"
"Ja, Bitte, thankyou..."
"Err...Your wristband, you have?"
Ah! Think on my feet and say allergic and say my girlfriend has them. Go back over to our table and ask her if she's clocked anything about EVERYBODY ELSE there. Of course I can see that they've all got wristbands on and can't believe we haven't clocked it. Must be a members/friend of the zoo kind of function or something.
By then though the alcohol is kicking in so we grab some more drinks, go and sit out of the way of the girl at the beer stall and get bladdered watching the hippos swimming around before quitting while we're ahead and end up in the Platz by the bombed out church where there is a stage and bars set-up and a free music festival on. Great day out.
