That is a very fantastic place, a great cave to taste the local life. I feel they are quite passionate.
The location is not far from Fira, i suggest to take the taxi to Fira, only 5 euros, very relax compare with the local bus, they did not respect the timetable, and it costs 1.6 Euros.

Tips: there are many dogs, 1,2,3, 4...maybe more. but they are very kind when they got your smell. haha
