this is a quaint old shop that proudly bears the emblem of its centurion status. its windows are a broad lattice of white wood and through the glass appears an array of jars – pots of conserves, jams and chutney stand in colorful succession. paul rothe and son serve sandwiches that aren't frilly, just wholesome assemblages of generously buttered bread with condiments and meats, vegetables or cheeses. i had slices of smoked salmon with a squeeze of lemon juice and pepper on a light rye whilst o settled on chicken mixes (basically the sandwich mix of the day) on thickly buttered granary. thus equipped and warmed after coffee and tea we headed to the national portrait gallery to see the taylor wessing photography exhibit.
