Visiting the Store and other locations

So I've traveled to Manhatten several times but never made the effort to visit to store and it's kind of on my bucket list. I found an old viewaskew link where it says to take the train but wonder if that's stil up to date. Also always wondered if it wouldn't be reasonable to do it by cab instead of train but I figure not. Would love to visit the Quickstop too while I'm there, maybe a cab ride from the store?. Anyone has any tips on how to get there? Maybe even someone wants to join in on it all ? I'm flying in from Belgium on the 15th of September
