Just had a Bad Boy Brisket and a side of beans. Beans were delicious, not just the ones out of a tin you get some places, and the burger was packed full of brisket and very tasty. They do gluten free buns, but make no claim to the filling being GF, so careful if you're strongly coeliac.
On top of that, they get the little things right, like the takeaway bag came with a set of bioplastic cutlery, and the customer service was super.
Live nearby so will be coming back for sure.
