alt Hacker NewsWhat is a meal though? Do you get the same volume of food from all vendors, and the same number of calories? I definitely order multiple items from restaurants that have small portion sizes, so I suspect some vendors would be better or worse deals even at a uniform price.
I don't know what goes on in the back end, but 7€ buys you what you get for more money at other music festivals, including from the exact same vendors.
