On Sunday, we're going to hang out with the kids in Battery Park. They are 9, 6, and 3 y/o, and they mostly like pizza, burgers, and Indian buffet. We (i.e., their parents) are open to anything (my wife will always find the grilled chicken in the menu, I'm more of experimental ;-).
I'm looking for a place in the very area where we could sit down comfortably and have nice affordable lunch.
Also, I was wondering if there are usually any food trucks in/near Battery Park over the weekend (particularly, Sunday).
