Left 4 Bread Location - Dying Light Easter Egg
In the Slums map of Dying Light there is a Bakery by the name of Left 4 Bread, this is an Easter Egg which references the Left 4 Dead series. You can find banners in a few locations throughout the Slums which advertise Left 4 Bread but the actual Bakery is found a little bit to the north of the tower just off of the one of the main roads that goes through the area.
Use the screenshot below of my map if you need help locating this bakery. If you search the bakery you'll learn that there is nothing unique to be found here; it's an Easter Egg in landmark alone.
