When Carolina and Oliver were about to go out to buy the materials requested by Andrew, Hector, the chef from the Heavenly Palace, came out of the kitchen and when he saw Carolina he smiled and handed her a list of food items.
Despite it being a new menu, Andrew had not asked them to create a whole new line, what he wanted was for 2-3 new dishes to be introduced to make the gathering feel special and unique to the guests.
Although it was true that only Alfi had hired the services of the Heavenly Palace and therefore they have no knowledge of the dishes served here, being young people of high social status it would not be unusual for them to find out somewhere and that is why Andrew wanted everything to be special.
