Water fountains and little food/drink kiosks are both great for small urban spaces. Water fountains tend to drown out the thrum of the city and make a place more relaxing and cozy, and little cafes etc. give people a reason to come and stay. Of course, the one necessary amenity that nobody wants to provide is a public bathroom.There's going to be retail inside of Winthrop Center itself, in the "connector". Seems redundant to have even more retail in the plaza.
