I used to get a bic mac large menu for me and my friend for roughly €10, now it's around €12 for one if i'm not mistaken (haven't been to the place for quite some years now).
The food was never worth the money, we went there for the friendship and low barrier of entry. We could just do what we wanted and enjoy ourselves for as long as we wanted. Watch some video's, have a laugh, maybe get a cheap icecream or milkshake after a while.
Where any regular coffee place would start trying to get you to order more or let you know they needed to "free up the table" for other guests.
Maccers never gave a shit and it felt good to be there, so that's what we did...we hung out as it was affordable, especially when the weather was bad.
