Farewell lunch in Berlin

I have always enjoyed french dining just off the Charlottenstrasse in central Berlin. Entrecote looks like a classic French brasserie and sounds like it, at times also. Both French and German are used interchangeably - so we maintained our tradition of ordering the menu du jour - a classic steak frites with a simple salad starter. I love the scattering of walnuts amidst the mustardy vinaigrette. I enjoy they way they slice the rare steak and place it in a rich gravy beside the slimmest crunchiest fries I have ever enjoyed. and the best is that they only serve half the portion at a time, keeping the second half warm and fresh - such simple and elegant style. It is, as always a wonderful way to enjoy a business lunch with both businessmen and tourists...
