Be prepared for the prices. No joke. It has gotten really really expensive, so just be prepared. You can easily spend nearly $100 a person for the day if you buy alcohol as well. The portions are tiny, but add up fast, so pace yourself, you will get full more quickly than you think. I highly recommend marking down the dishes you liked and then picking up the cookbook if it has those recipes. Also, often the random countries that have a booth like Austria or Poland will have shorter lines, but have great food. I've had some of the best goulash of my life at the festival.
