Well full disclosure we paid 90€/guest for a largish menu, there's plenty factor that are involved including head count and menu size, but average venues here were between 1k and 5k so even in a smallish wedding like ours food escalated quickly and reached over that cost.

We also ended up moving the wedding sunday which was weird but cut off some costs dramatically, we paid the stay for our international guests etc, so, as before, ymmv

I kept an Excel somewhere if people are interested in that sort of thing.
