We were given a tour of the kitchen and Jason greeted us and gave us a copy of his book which he signed for us as we were celebrating our 29th anniversary. Really top place and very good night out.
Can't see a restaurants 2012 thread - so will post here. Went to Pollen Street Social (near Oxford Circus tube, just off Regents Street) last night - probably about the best food I have had anywhere. Really outstanding.
