Let me start this review off by dispensing with some semantics: it says "grilled onions" on the menu. They're actually caramelized. Which is actually even better. But technically incorrect.

Moving on - and straight to the point - this is the best burger at Wild Brothers. There are no serious flaws with this masterpiece. The only very minor flaw I could come up with is that this burger is maybe slightly unbalanced due to the lack of veggies. Then again, judging by the spec sheet, that seems more of a feature than a bug. The hardcore artery-clogging vibe this burger exudes is the point. And it's great.
