Possibly the best post office in the world.
Bright and airy with fantastic architecture, it looks untouched. Staff are incredibly helpful and Uncle Ho looks down on you as you address your envelopes on the conveniently placed writing desks.
As well as the resting area shown there are old style phone booths, all red wood and glass and areas where you can buy collectible stamps, postcards and tourist treats. All it needs is a bar and a snack concession and I'd spend days in the place.
