Gordon Ramsay owns or runs 13 restaurants in the UK and 16 in other countries, making a total of 29 (though several of his restaurants have closed in the last year or two and new ones are opening, so it's hard to get up to date figures). He also owns several hotels, bars and has a number of other business interests.
Most of his UK restaurants are in London. Among the most famous establishments are the Savoy Grill and the restaurant Gordon Ramsay at Claridges. He has several others which are famous for having high profile chefs, like the Murano and the Petrus, each with a Michelin star, run by Angela Hartnett and Marcus Wareing respectively. Another top UK outlet is the Restaurant Gordon Ramsay, which has three starts and whose chef is Clare Smyth.
His international restaurants are largely in the US, but he has opened them in many countries including Australia, South Africa and Dubai.
