I love the idea of a multi-functional refreshment station. This combination consists of an espresso machine for the morning caffeine jolt and wine storage for the evening nightcap.
8. Butler's bar. Install a wine cooler and a coffee maker in your butler's pantry to have a bar area and a full-service center right at your or your guests' fingertips.
I like this idea (minus the wine cooloer) for a "coffee area" to house the coffee maker, microwave, toaster, etc... stuff we use everyday, but need out of the way of our main kitchen usage.
You mentioned putting your coffee machine in the second appliance garage in your design which is fine but that cabinet happens to be the perfect size for a built-in coffee machine such as this one if you want this as an upgrade sometime down the road. It would be right below your microwave unit for a great appliance center area.
