For NYC souvenirs with a twist, stop by this shop next to the stationmaster's office in Grand Central Terminal, which carries a comprehensive supply of swag themed to NYC public transit: mugs, T-shirts and hats for your favorite subway line, jewelry made from old tokens, bags and pencil cases, toy trains and much more.
They also feature a free gallery annex for the New York Transit Museum, with occasionally changing exhibits on subjects like the MTA's history, signage design or construction.
