The main selling point of the Portrait Restaurant is an amazing view over the city. Although when you book a table they say there are no guarantees of a window table – take fair warning now – unless you are a celebrity you may still be denied one even if there are several free when you arrive. The table allocation is shocking and the head of reservations, rude. Had we more time we would have eaten elsewhere on principle but having finally been seated at a compromise table (so Jon Snow could enjoy the view we had wanted and booked an early lunch time for) the food was very good and we had no complaints about the table service. If only the front of house could match the quality of the kitchen. Beware.
