Double Cow is the most expensive Burger, this one has no sweet sauce which I
like more than the other one. It is also made with nuts, walnuts in particular, which is still unusual for me. I might would like it even more without those nuts, but it might be healthier that way since they bring some Omega's I guess.
The Black bun is made with coal and it is not the Standard, they just had some of it that day and asked me if I would like to have them instead the normal ones.
