Very cool to find this already entered ;)
The joint specializes in cheeseburgers, and mine was actually pretty good by German standards. But you’re here for the two ticks. Friendly and cheerful service, it does seem like a nice enough place for outside sitting in the summer, and I expect you might find some good football convo here with the Stammkunden. One of the few places in Germany I’ve found to offer growlers to go, though they are expensive. Location makes this essentially a no-go for most tourists, but if you’re in the area, might consider this and its neighboring local "Strassenbahn", which has its own friendly and quirky charm.
