It's already been touted as the best burger in San Francisco, but now Spruce's burger is getting the promo treatment on Sunday nights. From Spruce: "Each week, we will open three boutique red burgundies from our extensive cellar and pour them for you to enjoy with San Francisco's best burger. Make your experience even more decadent by adding seared foie gras and house-cured pancetta to your burger. Spruce offers Burgers & Burgundy on Sunday evenings through November." [EaterWire]
