We have an L shaped kitchen diner - the kitchen is in bottom part of the L longer part is dining room. We currently have a wine cupboard which is in the kitchen design but is more in the dining room part. Neither myself not DH drink but it does have a place for recipe books along the side (but I tend to google recipes). It seems like wasted space and could potentially take it out and put a small 2 seater sofa facing the kitchen.
Do you have a small sofa in kitchen diner? Does it get used or does it just suck up space?
