Jamie Lafferty discovers a New York that is such a melting pot of new and established nationalities it's almost impossible to decide what's for lunch.
An Irishman, a Mexican and a Chinaman get on a train. They're joined by a bickering French couple; a black man with a shock of snow-white hair; a handful of very Caucasian ravers en route to a daytime party; a woman - I'd guess Somali - in a long, flowing abaya; a nervous-looking south-east Asian man with high, hard cheekbones; a crumpled Indian grandmother with an unruly grandchild; and me, a greying Scot, enormously satisfied that Line 7 of the New York City Subway, aka the International Express, is as ethnically diverse as its nickname suggests.
It starts (or ends) in Manhattan travelling to (or from) Flushing in Queens, stopping in dozens of different ethnic neighbourhoods en route, making it a kind of haphazard tour through New York City's remarkable multicultural cocktail.
I decide to start at the core of the Big Apple, at Times Square, Line 7's most westerly point. You could argue that this is the most international station of all - to stand in the middle of that mad, neon place is to stand at the centre of humanity, with skins of every shade, faiths of every bent and some frankly extraordinary body shapes whirling around at every hour of the day. In the city that never sleeps, it is a hub of cosmopolitan insomniacs.
But as exciting as Times Square is, things become better defined once the train has moved east, past Fifth Avenue and Grand Central Station, under the East River and into Queens. Since its foundation in 1624, New York has been a city of immigrants, arriving in different frequencies from different parts of the world. People didn't just land and stay in one spot - ghettos grew and diminished, settled and shifted. From the outset there was gradual migration as the city swallowed up more and more of its surroundings. It wasn't a neatly organised wave, but rather a pulsing, ever-evolving movement, more like a gradual tide.
If Manhattan is the epicentre, then the Line 7 stations and neighbourhoods closest to the river have seen the greatest migrations with people from Latin America and Asia spilling out towards Long Island. Before that, though, the Irish were here - and have largely remained in the Sunnyside neighbourhood, around the stations at 33rd and 40th Street.
Patrick McConville, proprietor of the newly opened butchers the Meat Boutique, has been in New York for seven years, though his thick Galway accent makes it sound more like seven minutes. Save for being a doorman or contract killer, I can't imagine him being anything other than a butcher. Bald, broad and built like a steamroller, you'd probably lose your hand at the wrist if you threw a punch at him. But there's also a warmth with him, and though it pains me to say it, no small amount of Irish charm.
He sources his meat from upstate New York, as close as he can to the city ("Y'know I haven't seen a cow in this town since I got here") and sells it alongside an array of Irish goods which he imports for fellow expats. "There's [Irish] folk come out from Manhattan, in from Long Island, up from Jersey - there's a good catchment area. But it's not all Irish people who come here, we're in between two or three stops for the train so at dinner time it's just nuts."
The Meat Boutique is wedged between two pubs, real Irish pubs, run and frequented by people from the homeland. "We're very tight knit, y'know? But there's a lot of Romanians and Albanians here too," the butcher says. "It's the most densely populated Romanian community in the US. But we all mix good, y'know?"
Within a few hundred yards there's American Diner, a Hispanic barber, an Asian threading salon, the Spanish Theatre and a Colombian bakery. Just when I think I've worked out that this is now a predominantly Hispanic neighbourhood I come across the corner of 43rd Street which is variously populated by Bangladeshi, Thai and Middle Eastern restaurants.
This highlights perhaps the most difficult thing about making multiple stops on the International Express: working out what to eat. In the interests of international diplomacy it seems only right to try as many as possible, eating at virtually every stop, whether that's a Lebanese manakeesh, a Mexican taco, a Sri Lankan dal, a Cantonese dim sum, a Bhutanese curry, a Colombian empanada or an Irish steak and Guinness pie.
Going into a supermarket doesn't help much - the Romanian Market just outside 40th Street station is home to Transylvanian cheeses, but also offerings from Macedonia, Bulgaria and Greece, as well as sausages from Poland, Hungary and Albania.
Moving further east, around 61st Street station, Sunnyside becomes Woodside and then suddenly Little Manila, home to more than 85,000 Filipinos. They're not alone, though - slews of Hispanic bars have also found space on Roosevelt Avenue, alongside the Ecuadorian consul and vast fleets of vans selling Mexican fast food.
The only constant amid all of this is the train, thundering overhead like a terrible storm, violently clattering through the stations as it boomerangs between Manhattan and Flushing.
By Jackson Heights another very clear shift happens: before even exiting the station I catch a whiff of spices carrying on the breeze. For several blocks around the station, one of the city's biggest south Asian communities brings a burst of colour, saffron-dyed beards and wizened yogis offering shonky advice to anyone willing to pay for it. It's predominantly an Indian community, but many Nepalese, Pakistanis and Afghans have found a place here too.
It seems appropriate that by the time the train screeches to a halt at the permanently bustling Flushing Station (the busiest outside of Manhattan) the largest community hails from the Far East. New York has several Chinatowns, but this is its most modern having only really been established in the 1970s. Today more than 40,000 Chinese immigrants live here, speaking at least 10 different versions of their language, eating several kilometres of noodles and a few tonnes of dumplings every day.
Unlike many Americanised versions of foreign cuisine the oriental food here remains utterly authentic, but not so strange that judges from the Zagat and Michelin guides are above recognising their high standard. Nan Xiang Xiao Long Bao is one of the best in the area, but to many it's known simply as The Dumpling House.
That's the trick on this line - to welcome everyone, to be truly international.
The writer was a guest of Westin.
Virgin Australia has a fare to New York for about $1830 return from Sydney and Melbourne including tax. Fly to Los Angeles (about 14hr) and then to New York (5hr 24min with Delta Airlines); see virginaustralia.com.au. Australians must apply for US travel authorisation before departure at https://esta.cbp.dhs.gov.
The newly refurbished Westin Grand Central allows for easy access to Manhattan's highlights as well as Line 7's second stop. While the hotel was celebrating its reopening, Grand Central Station has been celebrating its centenary. Double from $US399 ($435). See westinnewyorkgrandcentral.com.
CATCHING THE EXPRESS
Starting from Times Square, Line 7 takes 40 minutes to reach its eastern terminus in Queens. The majority of the track hangs over Roosevelt Avenue and some of the stations are so close it's worth walking between them, taking in as much as of the international mix as possible. A one-way ticket costs $US2.50; a seven-day, unlimited pass is $US30.
FIVE OTHER FAMOUS NYC ROUTES LINE 6
Running from Manhattan up to the Bronx, it has inspired songs, books and films, notably 1974 thriller The Taking of Pelham One Two Three.
For another foodie experience, the L train leads from Chelsea and Union Square through to Williamsburg in Brooklyn. Trendy food markets have popped up on the route (notably Smorgasburg in Williamsburg).
The dainty Shuttle Subway - Line 0 as it's sometimes called - is the shortest in the city, running a little more than a kilometre between Times Square and Grand Central Station. Ideal if it's raining, or you simply feel a bit lazy.
For a vintage experience, take the D train. Names such as Coney Island and Yankee Stadium fly past as it runs through its 41 stops. Fans of everyone from Bob Dylan to the Beastie Boys will have heard it sung about, too.
The longest route in the NYC subway system. It was once hijacked for 3½ hours by a man posing as a driver. He made 85 stops and arrived on time.
