When I lived in San Francisco I had a progressive dinner party with a friend that lived in my building. The evening started in my apartment, where we all gathered for aperitifs and canapes. Afterwards we moved to her apartment for dinner. It was a fun night, and I have always wanted to do it again. Last week I had an opportunity to do so as part of the London Restaurant Festival. The One Aldwych hotel invited me to enjoy a three-course dinner where each course was served in a different restaurant.
