I never thought I would see the day, but came across a site selling Pie and Mash, Jellied Eels, Stewed Eels etc.. on line.

Unfortuneately they won't deliver to anyone who live within a 10 radius of certain pie and mash shops, so that counts out most Londoners. Good idea for those who have moved away from London and yearn for the old tastes..
