Meat Liquor - This is near Bond street and heads up - no reservations accepted so there are often queues (everyone likes queues on wednesdays). A few friends have gone here and said it was worth the wait - for both the meat and the interior. This is a link to a review with lots of good pictures!!
Pie and Mash shops unique to the UK, Lovely meat pies with mashed potatoes and green (parsley) Liquor. I have had it delivered from this shop Manze, they deliver all over the UK and it's the original thing. Pie and Mash shops also serve Jellied Eels which is one thing I cannot stand!
