That is indeed what the New York Times has to say about the tourist potential of Zagreb. Shall we start with the backhanded compliments? Oh, we shall. Their travel writer Alex Crevar admires the "charms and chutzpah of an Old World city that is still coming to grips with modernity," and observes its "lack of tourism savoir-faire." But he does note that there is much good food and wine to be had, together with a pleasurable consumer and club scene. And he truthfully observes that "Zagreb was made for walking." Most importantly, he realizes that "there seem to be as many cafe-bars in Zagreb as people," which is good enough for me. But he misses my favorite restaurant, contact me personally if you want perfectly prepared high cuisine served to you while you sit on an Adolf Loos chair (for a pretty lipa, yes).
For a tepid summary of the promotion, have a gander at Večernjak.
