Hi

I have acquired a taste in Oysters in a big way.
But most of experiences happen to be:

Heathrow Airport having passed through Departure lounge
Schiphol Airport (Amsterdam, Holland)
Legal Seafood at Boston Logan International Airport (USA)
Restaurants on the coast of San Diego (USA)

I am interested in finding an Oyster bar in London
I am not really interested in a Dorchester Hotel experience. I am sure the
Oysters are fine, but the bill will be massive.
Neither do I wish to get food poisoning because the standards are lax.

Can anyone recommend an Oyster bar or two in London?

Thanks

Stephen Howe
