If you are in the chelsea area visit the chealsea market and in particutar the lobster place. It is not a restaurant per se but a fish market where you chose your fish anf they cook it for you for a small fee. I got two lobsters a dozen oysters (different varieties) one salmon salad and a ceasars salad all for usd93.00.
The food could not be any fresher. That for me is value for money
