Comptoir Gascon

63 Charterhouse St, London

At Pascal Aussignac’s Comptoir Gascon, the bistro version of full-blown restaurant Club Gascon, duck fat has always played a big part – and unsurprisingly, seeing as both the vibe and menu pay homage to the South of France. And the theme now extends to the new burger offering. A duck burger, in a brioche-like bun, is tender and juicy; the ‘Deluxe’ version is utterly indulgent – it includes a slab of pan-fried foie gras. No less decadent, the foie-gras burger (made with no other ingredient) is topped with truffle. Don’t forget the fries; as you might expect, they’re cooked in duck fat.
