Go to print-bingo.com and use their free tool to create fun mall bingo cards. All you have to do is type in at least 25 different things you are likely to see at a mall and their generator will create randomized bingo cards for you for FREE that you can print out.
Pass them out to all of your friends while sitting at the food court and when someone see something on the card they call it out. Everyone can then mark it if they have it on their card. The first person to get a bingo wins.
