Manhattan, an island 13.4 miles long and 2.3 miles at its widest, contains — as American poet Walt Whitman wrote in 1855 in another context — multitudes.

I visited three of them this week.
Midtown/49th Street:
Anchored by several iconic buildings — the New York Public Library, Grand Central Terminal and the Chrysler Building — this is a neighborhood devoted to sober-suited commerce. GCT, opened Feb. 2 1913, is the commuters’ cathedral, thronged daily by thousands of workers streaming in on Metr0-North Railroad from the northern and eastern suburbs of Westchester, (including my husband, Jose), and Connecticut.
The station — which every tourist must see! — is a magnificent bit of Beaux Arts design, with enormous gleaming metal chandeliers, marble stairs and the famous central information booth topped with a clock.

The ceiling is a stunning peacock turquoise, studded with tiny lights and painted with gold constellations.

This time of year, it also contains an indoor holiday market, whose vendors are carefully vetted and chosen. I look forward to it every year, and have gotten (and received) terrific, budget-friendly gifts from them.

Walk up Madison Avenue and it still feels like the 1940s, as you pass every possible iteration of elegant male garb: Brooks Brothers, Paul Stuart, J. Press, Mens Wearhouse, Pink shirts, Alden shoes.
I love Brooks Brothers, and have been shopping there since my early 20s when I’d fly in from Toronto and stock up on their cotton shirts. It has the prettiest ladies’ room I’ve ever seen. Paul Stuart clothing is mostly for the wealthy/creative crowd — network television producers or the heads of ad agencies, but it is spectacular, with shoes like these men’s bitter chocolate suede loafers ($625) or these wool socks, in 10 terrific colors, for $44.50.

Those few blocks have changed dramatically, not in outward appearance, but in their inhabitants — I once worked for the magazine in what was then the Newsweek building, a venerable magazine now dead. The headquarters of Conde Nast publishing were at 350 Madison when I first met editors there; now in their own building at 4 Times Square, they will move downtown to the newly-finished Freedom Tower, (built to replace the Twin Towers destroyed on 9/11.)
This is a part of town where the powerful meet one another in their private clubs, these few blocks a tightly-knit world of wealth, power and restricted access. Those open only to graduates of Yale, Princeton, Harvard and Cornell all lie within steps of each other. The Harvard club spans an entire city block, north to south. Step inside its doors (if you dare!) and you’ll viscerally understand the meaning of entitlement.
But walk along West 44th. Street to marvel at the windows of the New York Yacht Club, which resemble the rear windows of a galleon.
Two landmarks face one another at 49th and Fifth Avenue — St. Patrick’s Cathedral and Saks Fifth Avenue. Saks’ shoe department even has its own zip code, and offers a dizzying array of high-priced footwear. One pair of gem-encrusted, six-inch stilettos by Louboutin were offered at $3,200. The people-watching is great, from Russian oligarchs picking up multiple bags-full to the bare-legged beauty in her leopard coat and Gucci heels.
Uptown/70th. Street
The Upper East Side is a sphere of unapologetic wealth, law firm partners who use “summer” as a verb, (on Nantucket, the Hamptons, Martha’s Vineyard or Rhode Island,) of gleaming black Escalades ferrying hedge funders south to Wall Street and their quiet blond children to private school and their size 2 mothers to yoga or a hair appointment.
The streets are quiet, clean, manicured, filled with elegant townhouses, including that of soon to be ex-mayor Michael Bloomberg, at 17 E. 79th.
My former school, The New York School of Interior Design, is on 70th. street, and Neil’s Coffee Shop, 50 years old, sits at the corner of 70th and Lex, a great place for a burger or a cup of coffee in a classic china cup.
I loved NYSID. Classes were small, mostly female and the rigor of studying interior design seriously was sobering indeed. We had to memorize every floor, wall and furniture style from ancient Egypt to 1900 for a class called Historical Styles. (We, of course, nicknamed it Hysterical Styles, as we struggled to remember the difference between a cassone and a bergere.)
I whiled away a sunny afternoon among the one-per-centers — the woman calling Fed Ex to price the cost of overnight shipping her workout gear from San Francisco, the bright blond in a black mink shawl with a too-tightly-stretched face, the father and son carrying lacrosse sticks into their $114,000 Mercedes SUV, the weary sigh of a woman waiting a second too long for the valet to bring around her car.
I stopped into Creel & Gow, which sells quite extraordinary objects — like this diorama of a walrus.
Love this description of the UES, from the blog, Jeremiah’s Vanishing New York:
One of the things I like about the Upper East Side is that it remains so much itself. It’s not trying to be another neighborhood and it’s not trying to be cool. It’s filled with all kinds of tacky, expensive shops, and none of them are ironic. The rich people there, walking around in full-length furs, look like New Yorkers, and not like Europeans or Midwesterners trying to look like Europeans in New York.
There are also lots and lots of ancient white ladies toddling around, complaining about life, with their hands heavy with diamonds and their eyelids painted pink. They have great faces, and you can watch them go by from the window at Neil’s.
Essex Street
This is where it all began, where wave after wave of European immigrants landed in the narrow streets and crowded tenements of the Lower East Side.
Today, the LES is hipsterville, dotted with places like Babycakes, which sells vegan, gluten-free cupcakes, cookies and madeleines (made beneath the original pressed-tin ceiling) or candle-lit restaurant Dudley’s, where I perched at a curved marble-topped bar and enjoyed a tart cocktail made by a handsome red-haired bar-tender from small-town Ohio. There is even a small hotel here, The Blue Moon.
But come here for one of the city’s most moving recreations of urban life, the Tenement Museum, which powerfully explains the daily experience of the immigrants who lived here at the turn of the 19th. century.
Now that the temperature here has plummeted, the connective tissue between these disparate worlds — the status-agnostic subways and buses — is filling up with the homeless, of which New York has a shocking 50,000. They sit with their cardboard signs, pleading silently or asking out loud, apologizing or not.
In the eight years that billionaire mayor Michael Bloomberg — who often weekended in the Caribbean — was in power, the number of homeless New Yorkers rose by 65 percent; 21,000 children slept in shelters in January 2013, a new and sorry record.
It has become, increasingly, a city divided.
