Two questions:
1) Where do you park?
2) Any local restaurant advice?
1) They have ample parking on campus for a price (8-10 bucks for football games, basketball is probably the same) or park outside on the street opposite the Botanical Gardens and adjacent to the Fordham parking lot/garage for free (which is what I do).
2) Go to Arthur Avenue ( right outside the back gate) and you can't go wrong. Or if you are looking for a quick bite before/after the game Dagger John's in the basement of the McGinley Center which is in the same building as the gym has burgers, drinks and stuff like that.
