I bet it’s not so much the “extremely pretty” comment, but instead the “You eat with your eyes” comment.
Still no reason for them to have a conniption about it.
Ill bet this is a German idiom that is much more innocuous in native Deutsch
You eat with your eyes
Means the presentation of the food is the first thing you notice. Or so they say on a Chef Gordon Ramsey show. Me? The first thing I notice about food is quantity....but I eat at Denny’s more often than a fine dining place.
