Black cod, the signature dish at Tsunami Clapham

the food

Sushi, sashimi, robata.

A short, deliberate menu built around the day's catch and the binchotan grill. The miso-cured black cod has been a fixture since 2001. The wagyu and the sashimi platters get most of the press, but the bao and the tempura are why locals come back.

the bar

Cocktails, sake, the back wall of whisky.

The Lychee Rose Martini is the quiet best-seller. Old fashioneds are smoked over cherrywood at the table. The sake list runs from everyday Akashi-Tai to vintage Dassai daiginjo, and the Japanese whisky shelf rewards the curious.

The black cod is everything you've heard. Twenty years on we still book the same booth for our anniversary, and it never disappoints.
