Bryant Park, a public space commodity

Via Gothamist, the latest commercial makeover of Bryant Park...not too intrusive, actually, compared to other ads.

Which of our great New York public spaces carries the highest commercial premium? (i.e., which ones do corporate marketers like the most?) Bryant Park seems up there. Washington Square is growing. I saw a whole stack of Old Navy flimsy plastic dog bowls at Tomkins Square yesterday (and watched an adorable pitbull tear it to pieces). I think Union Square is definitely up there too. Does Times Square count? What about McCarren Pool?
