I was lucky enough to go here last night

The restaurant is the only 3 star Michelin Restaurant in London.

We went for the menu prestige

and spent over 4 hours at the table.
The only restaurant that I have been to that comes close to this is Le Quartier Francais, which I visited in South Africa a few months ago

Both restaurants feature in the best 50 restaurants in the world in 2006
http://www.theworlds50best.com/bestlist.aspx
Ramsey @13 and Le Quartier Francais @38
although they have slipped from their 2005 rankings
If I were to compare the two, I would say that they are on a par with food, but the service at Ramseys was exceptional. I would love to go again, but apparently getting a table is extremely difficult.
Next on the list is The Fat Duck

This is also a three star Michelin Restaurant and won the best restaurant award in 2005.
I would also like to go to Chez Bruce on Wandsworth Common
