The Bomber (now officially the world's coolest child) has introduced me to Wagamama, which has replaced the Ivy as foodies' favourite restaurant according to the Telegraph.
When there he eats gyoza, "five steamed, grilled chicken dumplings filled with cabbage, chinese leaf, chinese chives and water chestnut. served with a chilli, garlic, sesame and soy sauce".
Sounds like Potsticker Dumplings to me.
I think we need to visit Hoo Hing and add a home-prepared version to our repertoire if only for the sake of my bank balance.
