Baby Jalebi - very nice Pakistani food
Lady Dumpling
Four Corners - a bit overpriced but it's good pizza
Piel de Galina - nice fried chicken and they do this onion flower thing that's unusual but good (not sure if it'll be on the menu at the festival)
Hot dog stands - always great after a million drinks

I think you'll likely be able to find somewhere but best option would be (assuming you're walking from Gate D) to go to south park 2 via Paines and see if you spot anywhere on the way. The purple dots on the map are the camp site stewards that will also be able to help too
Toilets are less busy in South park if that helps?
First time I went I knew nothing about it, only got a ticket as I was helping my mate and his group out in the sales. I nearly didn't go but decided last minute I didn't want to waste the £200 or whatever a ticket was in 2014. I wasn't sure what to expect but the whole thing blew my mind!
I also by chance ended up next to a couple of people I knew from work in the Tuesday night queue. They ended up camping next to us and as one of them had been 5+ times before, knew her way around so I just followed. I "enjoyed" myself so much that by the end of the weekend I still hadn't learned where a single thing was. In fact I think I only started to get to grips with the site layout after my 3rd year.
Since then though I've been obsessed with following the build and even if I wanted to, I don't think I could keep myself away from it!
