Visitors to Manchester could be forgiven for thinking they are in San Francisco - and it is not just the trams.
Sun-kissed San Francisco is similar to rainy Manchester, the report says
A report says the North West city is the UK's most creative, while its Californian counterpart wins the honour in the US.
Manchester's notoriously rainy climate is at odds with that of sun-kissed San Francisco.
But the Boho Britain creativity index said the cities were very similar when it came to attracting creative people.
The index was created by the US economic regeneration expert Richard Florida, who measured the appeal of cities to the new creative class which he says indicate a city's economic health.
The three indicators are ethnic diversity, proportion of gay residents and the number of patent applications per head.

Both San Francisco's Castro area and Manchester's Canal Street are famous for their gay-friendliness with the latter featuring in the television series, Queer as Folk.
Europe's biggest gay and lesbian festival, EuroPride, is due to be held in the city later in 2003.
'Outside the norm'
Mr Florida said: "Most centres of technology-based business growth also have high concentrations of gay couples.
"What I have found is that straight men and women also look for a visibly gay community as an indication that a city is likely to be an exciting place to live.
"Creative, innovative and entrepreneurial activities tend to flourish in the same kinds of places that attract gays and others outside the norm.
"When people with varied backgrounds and attitudes collide, economic growth is likely."
