A new Anglo-American steakhouse with rooftop dining opens in Clapham High Street next week – and promises “the best steaks in South London”.

Franklin & Baines offers selection of grass-fed British steaks, dry-aged for a minimum of 28 days, ranging from a 200g hanger steak at £18.50 to a 700g tomahawk for two at £69 – all half-price on Tuesdays. The menu’s US influences include BBQ corn ribs and a chicken Caesar salad.

Drinks include house cocktails, American wines and English sparkling wines, while at weekends bottomless brunches and late-night live music and DJs will set the scene for partying.

Franklin & Baines is the brainchild of Olivier Cohen, owner of Bordelaise bistro in Tooting Broadway Market, and Ashley Letchford of Jam Tree pubs.

It takes its name from a famous American and a possibly forgotten Englishman associated with Clapham. The US founding father Benjamin Franklin conducted experiments on a Clapham Common pond around 1770, while Sir Frank Baines, architect of the MI5 and ICI buildings by Lambeth Bridge on Millbank, was resident a century ago.

A 50% soft opening offer from February 27–March 3 is already sold out, but it continues with 30% off food bills from March 5–9.
