Ever so slightly hidden away by Bank station, you just need to look for the lift with the name of the restaurants in italic by 1 Poultry.
The outside terrace area (heated in the winter) is beautiful and surrounded by a number of plants. There is an open rooftop (as long as it is not booked out for a private party) where you can see beautiful views of the City.
Decent selection of wines and cocktails to choose from. A peroni and a rose was only £11 so actually not that bad for such a lovely venue.
Didn’t eat there but restaurant (French cuisine) looked lovely inside and the restaurant offers a set menu of 2 courses for £28 or 3 courses for £32.
