A small place, but staffed by friendly people who can help you find the places in the new King's Cross development, and tell you about what's going on in the area.
There's also a large model of the current development, overlaid on an interactive screen, so you can see how the area has changed, or find all the housing. Worth a quick stop in if you're in the area and interested in the development.
They'll also give you a free guided tour - have a look at http://tours.kingscross.co.uk/ to book. read more
