Three medals: This is one of London’s best restaurants. Consider making a trip just to visit this restaurant.
Two medals: A favourite, and one we’ll visit again and again.
One medal: Good, and well worth considering if you’re nearby.
No medals: Average, and probably only worth it if you particularly like this kind of food and are in the neighbourhood.
“Avoid”: This is a bad place – bad food, overpriced and/or incompetently serviced. Don’t go here.
