Well I usually take Coke to Kebab since it's pretty cheap in the area where I usually eat Kebab.(close to school)
Coke NOK 10 ~ €1,2491
Roll Kebab NOK 30 ~ €3,7472
that's under €5 in total.
Maybe that's not cheap for some of our other european forumers, but by
norwegian standards that's just about as cheap as it gets.
