What are the names and locations of the parent restaurants that have outposts at the Red Hook fields? In particular, I would like to know where to find the quesadilla's that are sold by the two stands on the NW corner. They aren't quesadilla's as I know them, i.e. cheese and meat between two tortilla's, but rather a giant tortilla filled with cheese and meat and folded like a taco. Anyone know where I can find them during the week?
