La Marzocco Strada, Electronic Paddle, 3 Group espresso machine
Why you need it: La Marzocco is like the Alfa Romeo of espresso machines, and you, dear millionaire, are far too classy for a Lambo. The pumps have the same design as helicopter hydraulics, the controls are akin to deep-sea mining technology, and it looks way sexier than either of those things. Also, you need to serve three of your friends at once.
Why you don't: You could go with La Marz's slightly more affordable home-grade version (the GS/3, which is only about $7000), or you could just go to a coffee shop.
