Top Six: Places for black cod

So you fancy a taste of one of the London restaurant scene's finest dishes,

Nobu , Metropolitan Hotel, 19 Old Park Lane, W1 (020 7447 4747).
The Japanese-Peruvian restaurant which introduced us to this classic dish has just celebrated five years in London. The original black cod and still the best.

Sumosan , 26 Albemarle Street, W1 (020 7495 5999).
Mayfair newcomer that delivers its own version of the dark, treacly dish, alongside deliciously fresh sushi, sashimi and hand rolls.

E&O , 14 Blenheim Crescent, W11 (020 7229 5454).
Increasingly popular Notting Hill haunt where you can try the cod classic plus other oriental-inspired specialities, such as salt squid and green mango salad.

Zuma , 5 Raphael Street, SW7 (020 7584 1010).
Knightsbridge ladies who lunch can now push the famous fish dish around their plates, or order from the yakatori bar.

Ubon , 34 Westferry Circus, E14 (020 7719 7800).
If you can't get a table at Nobu, try the signature dish at its cheaper sister restaurant in Canary Wharf.

Tsunami , 5-7 Voltaire Road, SW4 (020 7978 1610).
Now benefiting from the expertise of ex-Nobu chef Singi Nakamura, the black cod here naturally inspires comparison. It's at least as good - and cheaper.
