I like food truck food, but not food truck prices. They don't charge brick and mortar prices, they charge more.
I agree completely on the prices. It costs more to eat from a food truck than an actual sit down restaurant with comparable food quality. That means waiting outside in potentially hot/cold/rainy/windy weather, usually not any tables to actually eat at, getting served in cheap boat trays or foil instead of an actual plate, terrible quality napkins, usually smaller portions, and sometimes highly questionable sanitary practices. And they still expect you to tip 20% + on the checkout screens despite the fact you are not getting any sort of wait service. I am a huge supporter of independent restaurateurs, but I'm pretty much out on food trucks unless it's out of necessity.
