I find the other review utterly baffling until I remembered that this bar/restaurant is under new management. I have spent a few nights here recently due to me doing some business in the area and have had some incredibly tasty food at not astronomical prices but what I liked more than anything was the warm welcome and the atmosphere offered by the staff.
Another time I was meeting my wife there for dinner and was held up leaving her in the restaurant on her own for an hour, when I eventually turned up she was sitting at the bar having a whale of a time with the staff and a couple of regulars and sampling a variety of interesting cocktails. Thoroughly recommend for food, drinks and staff.
The Trading House serves Modern British food in a pleasant contemporary setting with furniture by Conran and artwork by hot British artists like Gavin Turk and Maria Marshall gracing the walls.
