DK guides are impressive at first glance notably for the high picture content and inclusion of useful illustrated maps and guides. On occasions they've been picked up for inaccurate or outdated information, but there was little by way of errors we could pick out of the Croatian guide. Restaurant recommendations seemed pretty good.
If I had any criticism, it would be that several excellent places in Istria were entirely omitted, for no obvious reason. For example, the stunningly beautiful hill town of Groznjan, also home to many art galleries and a music festival, is accorded a brief entry that fails to do it justice, while other lovely hill towns fail to warrant a single mention.
