This is how it works. Each day the van's operators tweet its planned location that night. It might be placed next to a park or on a main street, but either way it'll be in an inner-city location near public transport.
For some reason the two I'm following, Beatbox Kitchen and Taco Truck, seem to hug the inner north rather than crossing the Yarra River. Presumably the grungy streetscapes of Brunswick are a better fit than the delicate facades of Albert Park, and I suspect the local councils in the north are more relaxed about permits for that reason.
Yesterday afternoon the call came, or in fact the tweet: "@beatboxkitchen: Dinner outside mr wilkinson, lygon st east Brunswick from 6pm". A little cryptic, but it turned out Mr Wilkinson was a bar at 295 Lygon St, East Brunswick.
I was slightly puzzled by this location - it was on a tram route, so easy to get to. However, I knew the footpaths there were average width and lined by shop fronts. Where would people eat, exactly?
The answer turned out to be quite clever. When I got to the burger truck's serving window, I saw this:
As people ordered, they were asked "Are you eating in the bar?" The van had formed a friendly arrangement with Mr Wilkinson - burger buyers could sit in the bar if they liked; and naturally, they tended to buy a drink while there.
This was the same methodology I followed. After placing my order, I went in and bought a schooner of Kirin ($5), then took it outside and used it to save a spot at the bar's narrow streetside stools while I waited for my burger. The resulting combination of beer and food looked like this:
The fries ($5) went cold too quickly, but that's always the danger with fries rather than thicker chips. The spicy mayo that came with them was good.
As for the atmosphere, it was a great vibe on a balmy spring evening, with people spread between the van and the bar and in a burger-induced good mood.
My next assignment - if I choose to accept it - is to track down the Taco Truck.
