At certain points, we explain things. But we don't talk from go to woe. Much of the experience of Hanoi is about allowing time for the brain to process the message from the eyes...or the nose...or the ears. If we yack too much, it interferes with that process.
But we do get a lot of questions.
Which we love answering.
Do people really eat that? Um...and what is it?
And then later, when our customers are relaxing back at their hotel, we send them some information from here and there, which they can peruse at their leisure.
I suppose you would call it 'after sales service'.
