Japan
One of the top-ten tourist sites in Japan offers a once-yearly evening festival where you can drink unlimited, locally produced sake for around a fiver.
Himeji castle itself was built in 1346 and was the first UNESCO site in Japan. What better way to spend a Saturday night than picknicking in its grounds?
Grab yourself a sake cup and some free senbe (Japanese crackers) and enjoy the Castle, the Moon and the company. Last year, I was told by a seasoned quaffer that the feeling of drinking sake can only be described as... "One, two, ten"... I wasn't sure what this meant, but I think it augured moderation, so take it easy.
Do however make sure that you try all of the sake on offer. It's all locally produced, is delicious and is ladelled out of wooden containers, rather than poured from the bottle.
The party starts when the sun goes down on October 3rd this year.
Travelling from Tokyo is a two-hour, direct Bullet Train ride (Himeji is also a good stop-off on the way to Hiroshima)
After that, it's ten Minutes on foot from Himeji JR Railway Station (central exit)
