They do seat you. We had lunch at BOG on July 4th -11:30. We were a party of 5 adults and were sat in the Ballroom which is where my granddaugther and her friend were hoping for. We did not specifically request it knowing that everyone wants to sit there. It’s lovely, but very large and very noisy. We were told we could stroll around and see the other 2 rooms. I really liked the Rose Gallery
