This truck, also a friterie/frituur was parked several blocks from the Belgian national stadium the other night during the Belgium - Macedonia game. As a matter of fact there were a few of these portable friteries and business was booming.
The typical Belgian snack, even full meal, is a big pack of frites (sometimes served in cone-shaped holders), a frikandelle (type of sausage) and/or a hamburger (deep fried with the fries) along with a soft drink or beer.
Sure, I love frites but I also love finding new and unusual friteries. I equate these to the diners back in my home state of Jersey.
