Woohoo! They showed up outside my building a few weeks ago
I spent the whole morning in hunger and agony of the 12pm availability after I saw the news on twitter where they'd be.
Everything here is simple so I won't dwell.
The service was fast and friendly. If you want your burger really fast get the pork one as they are pre-made, whereas the whole truck's are customized and take a bit longer.
I had a 2 patty whole truck and they dressed it exactly how I wanted it, even reading my awful writing of "extra" next to the aioli.
I also got the spiced your way fries, which I spiced, and they were delicious. They had some really interesting toppings you should try for them!
All in all, delicious burger that wasn't too greasy and surprisingly didn't put me into a coma after lunch!
