After 2018 Graspop (GMM) experience, I prepared this unofficial guide, I hope it'll be handy for other festival goers. I see everything is paid in tokens, how many tokens will I spend? GMM burger (quite big burger) - 4 tokens Hotdog - 2 tokens Pulled Pork Sandwich - 3 tokens Eggs and bacon - 3.5 tokens Jupiler 25 cl - 1 token Half-liter water - 1 token These prices are for standard food stalls. There are also food trucks that charge something between 3-4 tokens for food and 1.5 for beer. Food trucks are more tasty compared to standard stalls and a little less economical. Notice that 1 token was 2.85€ in 2018. I spent approximately 50 tokens during 4 days but I did not drink too much and skipped breakfast by eating at camp area. What I can find there as festival merchandise, how much they cost? There are tshirt, sweatshirt, belt, cap, bag, etc. Tshirt price was 20€ while sweatshirt was 40€. Notice that you won't pay it with tokens. I plan to see 40 bands in 4 d
