Although this Japanese restaurant may seem small and unpretentious in feel, it has everything it needs to succeed. Run by a young couple, Iwasaki boasts subtle yet decorative oriental-inspired details and a glass-fronted kitchen enabling guests to watch the methodical working methods of chef Tatsuya Iwasaki, who is fully focused on creating dishes that exude flavour, tradition and honesty. The cuisine here is based around two delicately prepared menus: Youkoso (midweek lunches only); and Omakase (lunch and dinner every day). Make sure you take the wine pairing advice of front-of-house manager and sommelier María José Vázquez.
