"The Union Street branch of Macellaio RC, which makes up part of Roberto Costa’s steakhouse group, doesn’t quite fit the blueprint of local Italian restaurants with their pasta-centric menus. But it is very much an Italian restaurant, with a prominent focus on exceptional Italian produce. Costa is well aware that Fassona beef from Piedmont is some of the best in the world, and is without the high prices of Kobe wagyu. For what’s easily one of the best steaks in London, go for the Fiorentina to be shared between two. The restaurant also offers a great selection of well-prepared offal dishes, if that’s your thing." - Jonathan Hatchman
