You're having a party, money no object, any frippery you want appearing as if by magic. What kind of party would it be, what theme, what food, what entertainment.
I'd have a medieval party, everyone would dress in medieval clothes, there'd be jugglers, fire eaters, and a guy with a mandolin singing a mournful madrigal wandering around. There'd be one huge table loaded with food - roast suckling pig, geese, lamb, salmon - mainly meat, they were big on meat those medievals
Everyone would overeat, get off their tits drunk on wine and mead, then there'd be dancing - medieval dancing of course
