Start with your current brewer and the mug you use every day. A useful home café makes a drink easier to prepare and the counter easier to reset; it does not require a new machine.
Count the mugs you actually use before adding a display rack. Cupboard storage, a freestanding tree and a small daily selection solve different problems.
A coffee corner works better when spoons, filters and packaged extras have a clear home. Use storage to support your routine, not to display every refill.
