I own a food truck, and I can say it's definitely not a 'boring' food venture, although it's definitely a lot cheaper than starting a physical location. You have to ensure that you can get decent parking spots for lunches, book good evening events or be willing to deal with drunkards on weekends, and be able to put out a good quality product quickly and efficiently. Getting the truck built out and going through inspections is nowhere near as expensive as doing so in a storefront, and you can run a much leaner crew (ours is me, my partner, one employee, and occasionally our spouses helping if needed - and I still have a day job on top of this).

We're doing fairly well for ourselves - nobody's getting rich, but it's fun and the income is enough to keep us from wanting to shut down, so I guess we're doing something right.
