It looks like Be Our Guest will no longer be a quick-service location and will not serve breakfast when the Magic Kingdom reopens on July 11th. In the past, this location was a quick-service location for breakfast and lunch and a table service location for dinner. Due to its incredible popularity, it was the first location to offer reservations for a quick-service meal. At this time, Disney is showing the same choices and prices ($62 per adult and $37 per child, age 3-9) being offered lunch and dinner for their 3-course prix fixe menu.
As of this time, Disney has not made an official announcement about the change but just quietly updated the menus and description on their website so we do not know if this is a permanent change or something that is just being tried during the phased reopening stages when physical distancing requirements are in place.
