Scents of Trastevere in the heart of Valletta. Zero Sei is the brainchild of a Roman family that has moved from the Italian capital with a fine baggage of culinary knowledge to the Mediterranean island. Therefore both Italian and international tourists can enjoy the chef’s sublime cacio e pepe and bucatini all’amatriciana (the best tasted on the island) just like the would in the Eternal City. No traditional wine list here: customers can pick among the many Italian wine labels – with a number of prestigious ones – directly from the wine cellar. The mark-up is reasonable.
