Went here on a Saturday morning. It took us 30 minutes to get to the ordering counter another 10-15 to get our food. The line wraps around into a small hallway that's "behind" the kitchen so it's kinda weird when people exit the kitchen and there's a door separating the line. I can tell it confuses people who assume the line is short only to find out it extends past that door.
The good thing is that it's a limited menu so there's not too many people holding up the line with their decisions. The assembly line is really fun to watch while waiting for your food. I got the sausage, egg, and cheese sandwich. Maybe it's because people hyped it up too much or maybe I should've got the #instaworthy Slut, but to me it wasn't great.
