My experience ranges from Scotland to Ukraine, Denmark to Italy and frankly haven't seen a huge difference. You see, modern culture became incredibly uniform. Global trends from TV made sure pretty much everywhere people are drinking the same drinks, listening to the same music, wearing the same clothes. I actually find it boring and no longer travel to cities when I am travelling for pleasure, not business, because today the only real difference between say Amsterdam and Rome is pretty old buildings. But otherwise people became "global people" everywhere.
The most interesting part is that I think we (EU) have evolved our own dialect of English, a non-native yet distinct dialect, which has its own words/terms like "wellness hotel" which don't exist in the native dialects (or were borrowed back recently). It differs even in pronounciation, "th" in words like think or three tends so sound like "s" in the EUnglish dialect, while in most native ones it is actually closer to "t".
