A good place to spend your summer nights in Kalymnos have some beers or any other drink listening to good old classic rock music is "Scorpions Pub" in Masouri.Oposite from the Plaza hotel 'Scorpions" offers a nice selection of beers,a veru nice environment to relax and hear to old school classic rock,have fun with your friends and so goes on.I highly recomend that place to all those who live or may visit the island as a nice way to spen your holiday nights.
Cheers!
