Looks like a Herbeau 4103 Single Handle Kitchen Faucet from the Estelle Series

I can't imagine a better faucet for this kitchen.

Here's the product description:
Based on an authentic 19th century design, the Estelle faucet combines 21st century convenience with retro good looks. Shown in polished nickel, the Estelle features a ceramic cartridge and an ADA-complaint single lever handle for easy flow control. Both the deck and wall mounted version are available in a choice of finishes.
