I came here around 1pm on a Wednesday, and the line wasn't bad. It went by pretty quickly, but almost all of their donuts (aside from the usual glaze, chocolate glaze, etc) were running out.
I ended up getting a dozen (mix of premium and non donuts = $25) to go to share with people later that day. For as much hype as this place gets, the donuts fell sort of flat. Some items you couldn't taste too much of the flavor (ex: maple lemon) - it just tasted like sugar - or others it was almost overwhelming (ex: raspberry vanilla and rum mojito are both pretty tart). Also, the red wine chocolate pudding one...does not contain a lot of pudding as an FYI.
I'm not sure if I would come back. Maybe you need to get the chicken and donut to get the whole experience, but the donut should stand on it's own too right? And hmm, I wasn't sold.
