My wife and I will be in London in September, and are having trouble finding an upscale, reasonably elegant restaurant that can accomodate vegans (heck, we're willing to be vegetarians and take in some egg and dairy product if needed, but no meat or fish.) Whenever I've been in London before since becoming vegan, I've eaten at low-brow Indian places -- but this is our anniversary weekend and I want to splurge.

We'll be staying at the Dorchester, but are willing to hoof it to go across London for a really great place. Money more or less no object; it's a special occasion.

Thanks for any suggestions.
