What kitchen island? The only one I see is at the very beginning when he's talking. If you want a metal one, you can buy one from a restaurant supplier, which you can find in the yellow pages.
In the opening credits where the "girl" is talking about meeting a chef at the store and cooking a meal for her boyfriend they show him standing at a wood topped island on a dark metal base with the actress. It looks like a maple top on cast iron.
