Observe how everything is hermetically sealed (to compensate for the delivery guy driving on the sidewalk and tormenting pedestrians like us):
Once you're finished eating, you just put everything back in the huge cooler container it arrived in: leftover food, plates, bowls, and cutlery. The delivery guy will come back later and pick it up. I think they need this in Canada!
PS -We will be venturing out today sometime so hopefully you'll see more than just food on my blog (fat chance of that happening)!
