Tackle shop central london

Am heading over to London for a few days-does anyone know of any good tackle shops in central London? Sea or fly fishing

Farlows is close to Piccadilly and Trafalgar Square, is a high end fly fishing shop and have a good saltwater lure selection.
For cheap gear Decathlon in Canada water,(on the Jubilee line) is worth a look. Have some good lure rods quite cheap.
