Sir might enjoy the oysters?
Astonishing though it is now, at the beginning of the 19th century oysters were cheap and very much a working class food. I suppose the change must have been well underway when Sheeky's oyster bar opened at the end of the 19th century. Joseph Sheekey was the market stall-holder who in 1893 was graciously allowed by Lord Salisbury to sell fish and shellfish on his new manor of St Martin's Court, provided he served meals to Salisbury's theatre-going pals. These days its reputation seems a little variable.
