Or while in one experience, in this example let's use your mention of iced coffee in Italy, you could be sipping iced coffee in a cafeteria and when you're done and turn from the next corner you could be witnessing a whole new experience that was determined to be something you would like as an user from past behaviour - just like we have google trying to determine our behaviour patterns in internet the same could apply here. So it would be a one seamless experience knitted together by different designers. And now that I think of it, we sure could be having and personal AI closely monitoring us and could act as one of the designers, perhaps slightly adjusting these designs to our personal likings.

E: And as you walk down the corner, after leaving the cafeteria, the change in environment could be gradual. The buildings could slowly change from ones from Italy to more akin to something from Mexico perhaps. This are all parameters that could be adjusted.
