Back in March/April of this year, The Belated Birthday Girl and I spent two weeks travelling between various European cities by train. Final stage of our journey: Thalys from Amsterdam to Paris for a quick lunch, and then Eurostar from Paris to London. (Photos 1 and 3 by The BBG, 2 by me.) More details here.
We couldn't be bothered paying to get in, but you can see some flamingos if you peek through the fence, and the outside features illustrations of monkeys and other, lesser animals. Both photos by The BBG.
