Andrew was so happy with the news that his three wives were pregnant that the celebration was so ostentatious. He spent a lot of money on the best ingredients for the food and had the best liquor he could find.
While it is said that he spent as much as he could on the celebration, the reality was that he had not spent much, as Candice being a food and liquor merchant brought everything from her store, so they did not spend much.
While Gaston and the others would have advised him not to spend such expensive ingredients in other circumstances, at this time it was appropriate, so they didn't even demur they went and got the stuff themselves.
Hector used the best of his skills and prepared exquisite dishes and the party lasted until after midnight. Andrew, Gaston, and most of the employees of the Heavenly Palace ended up drunk, as they drank more than they could handle.
