What would you do if money were no object and had no limiting conditions? It's not always an easy question to answer, is it? Because money, for most of us, is limited and does come with conditions (like being earmarked for rent, childcare and other necessities).
When I was asked the same question six years ago when I moved to San Francisco, I answered, "I'd volunteer for nonprofits, take cooking classes and entertain a lot more often." There's nothing wrong with that answer, but it wasn't as though it was meant to be taken seriously.
