A 5 Star dish can taste so good, it makes you hallucinate in a good way.

Lovely music can only fit along with a great dish. In Pre-OB, I was a master chef. :P I made 5 Star dishes along with great Strawberry milks and such. In fact, people begged for my food for dungeon effects.
So why not serve food at an orchestra? Of course, I might charge for a dinner, but it's not bad. I do need 23k for my cooking pot, after all.
