My wife and I are travelling to London the first week in December to visit our son, a college junior studying theatre at one of London's conservatories. We want to treat him (and a friend?) to a nice meal at a high end but hip restaurant. Cuisine is not an issue, nor is specific neighborhood, as long as the restaurant can be reached by tube or a reasonable cab ride. To the extent that more info might be a helpful guide, he has eaten at AZ, Babbo and Gramercy in New York and loved them all.
Thanks for the help.
