Henne Alt Berliner Wirtshaus has been around for over 100 years. It serves fantastic fried 1/2 chickens, along with your choice of tater or krautsalat (that’s cole slaw for you anglos 
), and fab Bavarian landbier in big steins.
It’s a personal favorite, and we usually visit more than once during our stays in Berlin. I cannot recommend it enough.
