Largo's interior, by designer Miguel Câncio Martins, features a gantry and lightbox above the entrance and three giant aquariums with jellyfish. More importantly, the kitchen is overseen by Miguel Castro e Silva, one of Portugal's top chefs. Dishes are prepared just so: Portuguese cod cooked at precisely 80ºC (176ºF) and served with fried breadcrumbs seasoned with wild mint and pennyroyal, say, or roast pork from the Iberian black pig with grilled polenta. The lunchtime executive menu is fantastic value at €18, and there's a good range of gin cocktails (from €7.50). There are smoking and non-smoking areas, plus free Wi-Fi and valet parking. Castro e Silva's talents are also now on display at his De Castro restaurants.
