I spent some time in Germany last year, and the pretzels/sauerkraut/doner/spaetzel/currywurst are all top notch.
But holy fuck, fleishkase. I haven't been able to stop thinking about it since I returned to the US. I've looked up how to make it several times, but it seems pretty complicated. Damn me and my lazy American tendencies.
That and the beer. I discovered that Dunkels are my fucking jam. Ugh, so good.
