So, I encourage you, if you're ever using a translator, in fact, just be mindful to maintain rapport and body language and eye contact with your intended audience, not your translator.
I think that it is nice for a guest to offer a beverage to the chef, and I think that this is really designed, and was originally to build rapport, and it's more of a friendly gesture.
You want to make sure you've built a sufficient amount of rapport before leading the conversation towards dreams in order to get truly meaningful responses.
