I like going to the mall for the food court, until recently, Charley's grilled subs was only found in malls in NYC. I love going to the Kings Plaza location.
I would visit Roosevelt Field in Long Island more often if it was easy to get to by public transportation from where I live in Brooklyn. It always has a lot of foot traffic whenever I go there.
Outside of food courts I only window shop at the regular stores in the mall. I do most shopping online.
