Food trucks were hack so people could start a restaurant without opening a building, and have since been co-opted by capitalism.

In Communism, if you want to start a restaurant, it would be easier since rent would be much lower/non-existent. There would also be no competition from giant corporations making shit food from a factory.

I personally would design the taxes/social structure so that lots of people opened up restaurants/food trucks. Food should be good, and people should be able to have fun making it
