• there are a few tables with bench seating in the Rose Gallery
• breakfast and lunch are CS, so you choose your own table. You can ask for a particular room for dinner, but if they are running near capacity (as they usually are) you will have to take what you get.
• after your meal, as long as you don't disrupt the other diners or get in the way of the servers. The Rose Gallery is sometimes closed off at dinner time.
• the beast is in his study for photos from the beginning of dinner until closing.
• I've never heard of this. Given the huge numbers of guests going thru the restaurant every day, I highly doubt it.
