Any successful arrival on the continent generates another batch of favourites, if that's possible.
I may be unusual, but the people matter more to me than the quality of the refreshments.
I was going to suggest a few airfields, but it just became a list of almost every European airfield I've been to, because just about all those visited thus far have been, typically, mixed-use, friendly, grass and amenable to a tent beneath the wing...just like airfields should be everywhere.
I would definitely include St Michaelisdonn in Germany -and for the wolf who lives on the roof of the tower. And some undeserved Teutonic, generous hospitality.
Sorry, QDM. With pleasant recollections of these and other arfields I think the rosy glow precludes a more sensible response!
