If you're a coffee junky, you have to get a Nespresso machine. If I could afford the automatic ones, I'd go that route, but I am very happy with my basic model - makes a perfect cup of espresso every time, and the pods are so much fun to use! If you're having a lot of people over for dinner, this machine just makes coffee so much easier. They have both regular and decaf, and several different strengths so you can decide whether you need a slight pick-me-up, or a powerful punch of energy.
The Nespresso staff is very courteous and professional, and you can try whatever blend of coffee you like in their store. The newest location on Madison should hopefully be open soon so it won't feel like walking into an office building.
