Yes. There is bias in this sampling method.
Let's break the question down.
Restaurant chain: place to buy FOOD
franchise in your town: PLACE they want to open a restaurant
want to find out how often people in your town go out to eat: the question
a researcher: guy interviewing people
interviews people leaving a local restaurant: NON-random people being interviewed
the problem here is that people want to open a RESTAURANT. And if you interview people leaving a RESTAURANT, there's bias because the people just ate there. The owners must interview random people in town.
