Vaporetto, a “Venetian diner”, is set to open 25 April in the former Mimmo d’Ischia space in Belgravia. Owner Gino Santini, who opened Santini in 1984, has partnered with Joseph Ettegudi, founder of the Joseph retail shops (we’re still waiting to hear what he has planned for the Mirabelle space he acquired some time ago from Marco Pierre White), for the concept, so we're not surprised to hear Vaporetto will be elegantly casual, midpriced and easygoing. You may remember the head chef, Stefano Cavallini, from his time at The Halkin hotel and I Sapori di Stefano Cavallini, a deli in Clapham (61 Elizabeth St., SW1, 020-7730 5406).
