I'm taking my 62 year old mother for a day in London in early December. She wants to do a bit of shopping, maybe go to a museum or 2, etc. I would like to treat her to a nice lunch somewhere and wondered if the hive had any ideas. I would somewhere "nice" rather than cool/trendy that does simple, good food would be good, I remember that Claridges used to do lunch for £30 which would have been ideal but sadly said offer is no more. A central location would be good to save going too far out on the tubes.
Thanks in advance for your help.
