Another place I've had my eye on is Barley Swine -

Look at their open table reservation status. All of the reasonable times are pretty much booked through to the next month!
I've heard pretty good things about barley swine, though, and the chef's been getting a lot of accolades recently.
I'm usually a walk in on a whim kind of guy when it comes to restaurants and I hate reserving things days or weeks or months in advance, which is why I've been putting off visiting barley swine.
