I don't know about Oahu, but in Kauai Food trucks have become a joke to me. The food is many  times cost more than it's brick and mortar counter parts and there are no wash room facilities. How the  state board of health allows this is beyond me?  Food trucks used to be a viable cheap alternative to  regular restaurants. You would get discounted prices because the food establishments didn't have as much overhead.  Now someone buys an old step-van and converts it to a food truck and they are a four star chef charging fine dining prices. I'd take fast food over any food truck any day, at least they have clean rest rooms  and quality control of the food. The state board of health needs to take control of the food truck revolution.
