I saw an interesting thread about big 4 cities in each country and as a non-European who visits often, I found it very interesting and sometimes surprising. I wonder how would a tourist big 4 differ.
This seemed to originate from a U.S. question as to the big 4 cities being New York, Los Angeles, Chicago with much debate about the fourth. From a tourist perspective, I would think the top 2 would still be NY and LA, but the next two probably between Chicago, San Francisco, and DC. Thoughts about your country?
