We have both a butler's pantry and a walk in closet pantry. Both are indispensable to us.
Also mandatory, a big single sink, efficient hood/fan, natural ligh. Refrigerator WITHOUT water dispenser or ice maker in door. GAS stove.
A DOOR that allows you to shut off kitchen and it sounds and smells.
As described above, a pastry/pasta making work space several inches below counter height. in our case, a marble topped table in center of room works for me.
Our kitchen is not new or chic but it works.
