The Don is one of those “old” city lunch restaurants that has been around for years and has got a loyal clientele (I think mainly the older generation that started going to Don when no other restaurants in the city were available). The Don is located close to Bank station and there is a more casual brasserie and a more formal restaurant next to it, located in a courtyard, so more secluded. We went to the more formal restaurant for lunch.
The décor in the restaurants is quite nice, there are colourful paintings (including seven original Hoyland paintings), blue long, quite comfortable chairs, white tablecloths, a standard city lunch setting. The food is modern French/ British and starters are £10 on average and main courses a bit more than £20, so standard for the city.
