Once upon a time, I worked in an office building (in South Dakota). At lunch time, in the lunch room was somebody selling food. Everyday was someone/somethine different. Wasn't a huge set up, just a table and depending on what they were serving. example one guy had a rice cooker with rice and a roaster with teriyaki chicken.
So my question, has anybody done this? I know that food trucks are becoming widely popular, but I'm wondering if this sort of point of sale catering lunch service is a viable idea?
