Have been hearing good things about the new chef at the North Nineteen (off Hornsey Road).
Menu has some Tibetan dishes (stir fries, noodles and momo dumplings), as well as Thai curries and some classic British pub grub too. All affordable and cooked from fresh. They're still doing their £10 Sunday roasts too.
