Since opening their first location in Ljubljana in 1998, Slovenia's number one proprietor of grilled vertical meat now runs dozens of restaurants throughout the country. Most, such as the one in Celje opposite the town hall, are little more than a stand catering to students and late night partygoers, but they're fast, clean and cheap, and there's a good chance that a 4am kebap will be one of the best things you've ever tasted.
