The receptionist set up an appointment for the Doctor at Alphonse's restaurant when he asked for a table on the balcony with a view of the towers, putting into motion his long-delayed date with River Song on Darillium. However, the receptionist indicated the restaurant was fully booked until Christmas Day in four years' time. The Doctor happily agreed to this appointment, using the TARDIS to skip the wait.
Four years later, the receptionist, who by now was sporting a new hairstyle, directed River to her table on the balcony, where the Doctor was waiting for her. Informed of her formal title, the receptionist addressed River as "Professor Song". When River asked if she and the Doctor had a good table, the receptionist replied that it was "the finest in all the galaxy". River told the receptionist to wait a moment as she got ready for her date with a special clothes-altering perfume, then left to meet the Doctor. (TV: The Husbands of River Song)
