How much would you pay for a sandwich? If you're one of the well-heeled city slickers who flood this hyped lunch spot every workday, the answer is quite a bit. Yet Earl proudly elevates the humble sambo into a multi-faceted cuisine. Hefty Stoneground bread is packed with designer fillings. Flaky morsels of harissa-rubbed lamb might be lifted by quince, zingy yoghurt, almonds and sprigs of coriander, and beer-battered athead by crunchy cos and preserved-lemon tartare. Salads can be somewhat hit and miss. Get in early for the pick of the sweets - macarons, friands, or dense polenta cake.
