In the south of Hungary is a very small city called Szigetvar and somewhere there you'll maybe find the gypsy bar Magasles.
It is run by a very friendly lady called Eva and if you're lucky a very old gypsy will play the violin - like, all night long. And the nights are long in this place.
Be sure to know enough hungarian to order a beer (Sör), wine ("bor") or the locally brewed palinka (if you like a glass of glue) because it's the only language spoken there.

No dogs allowed (except mine).
