Katrina's bar, just off the main 'street' of Ksamili is a little bar that I seem to remember being attached to someone's home. Plenty of beer and raki on offer, and I think that snacks might be available too.
Tani's, in Ksamili, is a bar, a shop and a guest house all rolled into one. The family are lovely, and Tani and his brother both speak English very well. Have your morning coffee (in a tiny cup and terrifyingly strong) here, watching the older men drink theirs while playing chess; and then come back in the evening for a few drinks - local or imported beer (not so cheap), Raki (50lek a shot, and shots aren't small!), or Pon? (pronounced ponch) , a strange, sweet, sticky, orange liqueur - while listening to music.
