Spruce

A little pricey, yes, but the accurately—if uninspired—named Spruce Burger at Spruce is a delicious indulgence.

If you haven't made reservations, you can always sit at the bar if there is an opening.  Also, the cocktail/lounge area is fair game for dining, as well, which is where I sat on this visit. There's also a giant framed photograph of the back of a man's head.
