Here is Nigeria, we do not have food truck but we have eateries cafe and mama put(Road side food vendors) I hardly eat in mama put because mist if them don't appeal hygienic enough for me but my friends how had tried a few of them said the food was great.
I would rather snack on gala(sausage rolls) and carbonated drink than to eat in an unhygienic restaurant. Not all of the mama put are unhygienic though, maybe I have not been paying attention because I hardly eat out.
