On Palmoticeva Street in Old Dubrovnik, D'Vino wine bar exists, simply being great. We dropped in after some friends in Mostar recommended it.
They specialize in Croatian wine and education. Their manager or owner or whatever (pictured above standing) lectures the occupants of this small enoteca on the finer points of Croatian wine and his views on wine in general. He is funny, charismatic, smart, and tough to figure out. I attempted to understand how an Aussie ends up running Dubrovnik's best wine bar, and so I asked him how he got there. He said "Lots of flights - Melbourne, Singapore, Frankfurt, Zagreb, and finally Dubrovnik."
Croatia has incredible wines and having D'Vino explains it makes the experience that much better. Also, there cheese platters are TDF.
