Coffee is a bit more simple and one can usually get away with regular and decaf. I prefer a dark roasted bean, and it's very easy to add a splash of hot water if the coffee is too strong. I also keep a tin of Cafe du Monde's Coffee and Chicory. It's a New Orleans favorite and I love the nutty taste, especially to cut through sweets (like a breakfast beignete !).
Of course it's helpful to keep sugar, sweetners, a cream pitcher, a thermos, your french press, and of course mugs, all within reach. I even like to have a toast rack nearby for a quick breakfast tray. As you can imagine, this cabinet is my first stop in the morning!
