Yes! There is a program that you get at the entrance gates during the festival that lists where all the kiosks are and what is being served at each. The first day I'm there (usually, I do this at my hotel because I always get in at like 10PM) I grab the program and cross out all the things I can't eat (allergies, dietary restrictions). I then circle all the things I absolutely *must* try, and then I check all the events that are happening during the time I'll be there. After figuring out where I need to be when, I now have a plan to make the 2.2 miles of the festival a lot less daunting.
Oh, and it's a good idea to stagger your kiosk purchases, ie: get food at one and alcohol at the next. Don't get both at the same time, alternate on your next walk around. It's very hard to walk and eat when you've got a plate in one hand and a drink in the other, and you can get drunk VERY quickly if you get something alcoholic at EVERY kiosk.
