I live a few blocks away so thought I'd try it for breakfast a few days ago. Let me start by saying the food is quite good. It's not a bad value either - $6.99 for breakfast.
But you might as well eat in. The drive-through is going to take ten minutes to get your order ready, and it takes about four minutes before they even take your money. This is not fast food by any means. Arguably it's not supposed to be, and that's fine... but why bother at that point? I've found that a few places in this area have slow drive through, but this place is by far the worst.
Eat, enjoy, but don't bother doing it in your car.
