A food container has a box base with four side panels and four bottom flaps extending from the respective side panels to close the floor of the box base leaving the top open. The bottom flaps are so designed and glued together that the box sides can be folded flat for stacking and then unfolded into a box structure having its bottom wall closed automatically. The box base provides food-receiving area while carrying and serving the eatery. Raised from the top of the box base are circumferential edges defining a tray top. The tray top carries out the decorative role when it is popped open as is possible thanks to the inventive folding scheme implemented in the tray top. The tray top also has carrying handles for the user. The front face of the tray top in the serving mode can be decorated with various cutouts shaped as interesting objects.
