Draught lager, yes, this was available in 2007 from 'On The Rocks', just past the Sirokko taverna (Hello Babis). They sell the Athenian Craft beer, in several varieties, including their 'red' beer.
They claim to be a micro brewery, but I have seen their beers on sale throughout Greece, and I am sure 'micro brewery' should not be so widely available.
I am hoping to return to Plakias in 2010, having been away too long, but I HAD to go to Lesvos to restock my supplies of ouzo. Lesvos is the place the best ouzo is made, and I can recommend Petra to all who like Plakias.
Here's hoping for Olympic to offer some good deals to Kostas Chrysoulla in the very near future, may see you all in June 2010.
