If it's the building numbered 207 then something is happening in there.
You know how it is around here, you go on holiday for 2 weeks and come back to find someone has opened an award winning restaurant, hosted several royals and Hollywood stars and had a food poisoning outbreak, while you were sunning yourself in Skeggy.
The Delaunay Counter - which is the takeaway or sit down cafe next door has 50% off at the moment whilst they train the staff. None of the grandeur of the restaurant next door but a very economical way to sample some of the fantastic pastries they do. They also serve breakfast - well worth a visit in the next few days - I did ask when the 50% deal would finish but it hasn't been not decided yet so be quick!
As for the Delaunay .. I didn't think it was that expensive. I usually have a Pretzel, the Chicken Soup (which is simple but one of the best offerings I have had in London so far) and dessert. I am usually out of there for £20 ... now admittedly it could get very very pricy but I guess I am a cheap date ;)
