Visiting Japan (suburbs, not city) was like visiting a sort of parallel universe. Everything was fundamentally similar, but totally different. Additionally, I was learning Japanese at the time, so it was rather exciting just trying to converse with native speakers. It was quite a while ago so I can't think of much in the way of specific examples of the 'bests', but they have a number of cultural aspects and traditions I preferred over their western equivalents, such as sleeping accommodations and choice in breakfast foods. (always found most western breakfasts beyond cereal/oatmeal and toast despicable)
Providence. Spent the week with a girl, roaming around the city a bit.
