It might look formal but this venue presents no barrier to casual dining
Part of the Balmoral Hotel, Hadrian’s has been a dependable presence on the capital’s dining scene since 1997. The décor is tasteful and contemporary while the menus cover everything from a quick business lunch to pre-theatre, à la carte to something for the children. The cuisine is modern European; a typical main might be cod with black olive and herb crust, crushed Brussels sprouts, citrus and Avruga sauce.
