We stayed in Motel One near the Hauptbahnhof, Berlin. 3 restaurants:
1) Wildes-Fraulein - an alpine-themed restaurant, good food
2) Zoolpackhof - very traditional place, exceptional food
3) Neumann's - old fashioned tavern with very good food
All are an easy walk, any would be a good choice. Zoolpackhof is the best
