I was there with my kids last week. 2pm Friday reservation, and it was, indeed, a seat yourself QSR restaurant during lunch. I booked the reservation 6-months to the day, but overlooked that it was a QSR until a month later. Still 5-months out, I was unable to change to another lunch the entire week (June 6-11, 2017), so I guess it's still a good idea to book far out.
Food is ordered on a kiosk and brought "by magic," a very helpful kiosk CM told me. They must read the RF chip in the magic band to find which of the 3 rooms we were in. Seating at 2pm was no problem whatsoever in 2 of the 3 rooms. I was concerned based on the line leading up to the kiosks, but plenty of seating - except the West Wing. People were waiting outside and hovering for folks to leave.
Not bad, but I would have preferred a dinner table-service (TS) setting.
