Best burger in Europe?

I’m not a big fan of burgers and in fact don’t think I have ever been to a.burger bar before. However I’d had little sleep and an early start to get to Copenhagen and this tiny burger place in a gas station opposite my hotel is supposed to have the best burgers in Europe. I skipped the planned evening trip to Mozart’s Requiem as I have suddenly developed something like eczema including on my eyelids so I went back to my minimalist hotel and covered my face in BioIul which relieved the itching.
