What is your favorite city?

I was talking to my grandmother the other day about favorites places I've been and she asked me if there was any places I didn't particularly like. I guessed Tokyo because it was so expensive. But what is my favorite city? Very hard to say...it's like trying to pick your favorite child, but I would say Sydney and New York City are my top two choices. Boston, Cape Town, Buenos Aires, and San Diego are probably my third favorites! It's hard to say.
