Wow, thanks for the 2 leads. Having lived in NYC for 3 years now, I only know of the famous FPH also my other favorite, Altman Luggage. During the time I lived here, I have had the misfortune of witnessing both Joon and Art Brown shuttering.
Altman is an interesting place because they have a small side business in pens. They do have quite a wide range but many are not displayed and you have to ask. They are also very generous with the discounts, typically 5-10% more than the industry standard 20% off list. The only unfortunate thing is that they only stock their pens in F and M. So you're out of luck if you're a fan of B and Stub nibs.
I typically don't go to Kinokuniya for their fountain pens. They have a dismal selection and prices are FULL retail. And it's retail when the yen was at it's peak. Go for their wide range of inexpensive amazing Japanese pens and pencils, stationery and most of all notebooks. They have Midori, Marumen, Life and a few other brands that escape me at the moment.
Also don't forget the flagship stores of all the top brands, such as Montblanc, Smythson, Cartier, Louis Vuitton, Hermes etc. They all carry fountain pens and have the best selection in the country. Of all the brands, Montblanc is the best because they have a tester set they encourage you to try, as does Hermes. Cartier and Louis Vuiton don't see to be as interested to sell their pens. But if you're interested to touch and see, and perhaps get their folders, folios or paper products, this is the place to do it.
