One of the best things about showing in New York is that I've made lots of new friends stateside, so it basically means that for the 12 days I stay there, I try and go out as much as possible and see everyone. Not only all my US friends, but there is always a big group of my friends from the UK who travel out there too, and it's so rare that we all get to hang out, so it does turn into a pretty big social event.
I also tend to have a list of places I want to see, eat at, shop at etc, so try and make the most of it. One of my faves is Russ & Daughters. It's great, not only is the interior a Wes Anderson-esque dream but the food is sooo good and it's also pretty much a graphic designers wet dream!
