Richoux on Brompton Road is one of my favourite restaurants, and I make a point of going there whenever I visit London (whether I decide to walk across the street to Harrods or not!). Richoux has the most comfortable, casual elegance in ambience and decor, has great servers who are always pleasant, and, of course, good food. I confess I have not been to Richoux for dinner, but for breakfast, lunch or tea, it is one of the most comfortable places for a solo-traveling female to dine. I think many local residents are customers there, as well -- and that says a lot to me. I took some pictures this time (April 2007) so I can remember the look and feel of Richoux til the next time!
