I love the Marunochi area. You don't have to go into the French patisseries and high end stores -- the greens and the beautiful buildings can be enjoyed for free. And if you do want to eat macarons and buy a fancy purse, those are here, too, along with a few museums. Both worlds.
I had fun just walking along the sidewalk, dodging salarymen in black suits going from one office to the next (with one or two in bicycles). When night fell, the trees were lit up with Christmas lights. It was awesome. And to think I was just killing time.
