Have a taste of the best tortillas in Madrid, with tortilla options you would have never imagined and excellent Spanish jamón at modern, funky restaurant Flash Flash. Review 4 February 2014: “Fantastic omelets!! It's quite posh, very nice atmosphere though. They have lots of omelets (tortillas) to choose from; had the courgette/aubergine one and it was the best omelette I have ever had. And I have had quite a few. Also very nice big salads - you can create your own."
