I'm meeting an old uni friend next Saturday in London. In the morning I'm going shopping and to lunch with DS2, we will probably go to the Royal Academy after lunch. Friend is coming along at 4pm (she is doing something until then) We have a lot of catching up to do, maybe over tea or cocktails, can anyone recommend somewhere nice to sit and chat with the possibility of light food if we want it later? i don't really want to be somewhere too crowded. All suggestions gratefully received.
