An upmarket pub and restaurant boasting a Basque chef, its own branded caviar and state-of-the-art draught Guinness opens in Belgravia next week. The Prince Arthur, in Pimlico Road, also has a fishmonger counter in the bar offering seafood from Spain and Cornwall to eat in or take home.

The venue is divided into ‘The Pub Below’ for snacks, small plates, beers including Guinness and Hawkstone, cocktails and wine, and ‘The Restaurant Upstairs’, for larger plates cooked over a wood grill including lobster rice, whole turbot, presa Iberica and British ex-dairy Txuleta beef.

Basque-born chef Adam Iglesias has worked at restaurant Alameda in San Sebastian and in France and Australia before spending time in the kitchens at Barrafina and Brat in London. His luxury creations include such small plates as tuna, caviar and urchin with turbot dripping potatoes at £25 a pop, while more unusual seafood delicacies include baby eels, barnacles and Spanish carabineros prawns.

The Prince Arthur opens on Wednesday 15 January.
