Cardiff, Wales. One of the few places in the world that felt like a Real City while also having its own distinct culture and feel. Every other city I’ve been to feels like the same sort of dull corpo-district monoculture.
Old Montreal also has a bit of this, but only the central city areas, the outside periphery quickly devolves back into the “this could be anywhere in North America (version francaise)”
Trust me, if you go to Japan you will go to a 7-11 whether you want to or not. They are absolutely everywhere, like “ubiquitous” is an understatement. I think when we were there we went to 2-5 convenience stores per day just because they were just so… convenient…
