It seems that Teddie is trying to get Rei's affection and it has come down to a trading showdown with Zen, with you offering to help Zen. This request has a bonus if you trade in the right order, but know that it is impossible to fail this quest. Once you've accepted the request, go to the Stroll option and pick "A Trading Contest!"
Rei will mention that she wants something to eat, and it better be super-sized, with your starting item being a pair of chopsticks. You can only trade with up to three people, after which, the trading will end. Choose to go to the food court and you will go through a bunch of people, seeing what they want and have to trade. To get the best result and the bonus items, trade with Junpei first, Ken second and then Yosuke/Kanji last.
