There’s a branch in Buckingham Palace Road, just across from Victoria Station. I chose the rare roast beef sandwich, which comes on brown bread with beef tomato, watercress and horseradish sauce. I asked for mustard as well as horseradish. It was good, chunky with beef, but way too much bread for my tastes. I’d prefer thinner, moister bread, but not everyone agrees. I drank Cullinan View chenin blanc with it; very good value at the price.
