A Butler’s Pantry is basically a smaller kitchen, or walk-in pantry, within your actual kitchen. It’s large enough to house an optional second sink (perfect for hiding dirty dishes during a dinner party!) or dishwasher, and includes plenty of storage for kitchenware and appliances, plus additional bench space for prep work.
Think of it as the room-equivalent of that space underneath the bed that keeps your bedroom looking tidy. It’s essentially the gift of a cleaner kitchen.
