London: solo upscale lunch suggestions?
My partner and I will be visiting London (from Western Canada) for a few days; she is attending a conference and I am just going for fun. For several days she will be busy at the conference and I will need to eat alone for lunch. We have dinner reservations at Rasoi and at The Square, and I was hoping to be able to check out some of London's other fine restaurants for *relatively* inexpensive lunches.
Any particularly good spots for solo lunches? The criteria: should treat solo guests well, should not be too exposed a room (or should have a bar at which one can eat---I always feel a bit self-conscious when eating alone), preferably not too too expensive for lunch (say, 60 pounds or less), and hopefully reasonably close to our hotel in the Knightsbridge area. I prefer innovative to classic. Will only have "business casual" attire (including a jacket, but not a tie) with me, as opposed to a full-blown suit.
Thanks much for any suggestions.
