It's quite good.
I've got to high-light the Lyonnaise potatoes. They are excellent. I've had these several times and they don't disappoint.
Beyond that, the food is good, the environment is decent, and the servers are nice. Breakfast, of course, is their speciality. There are lots of options to try, like choice of toast: white, wheat, Italian, or English muffin (Italian is the correct answer!).
Don't be put off by the hype - this place draws people in for good reason.
