Schengen Visa at Greek Embassy

Dear Members,
A question to the schengen experts.
Below is my travel plan for a single trip.

France- 1/2 day
Italy-1 day
Greece-7 days.

Going by the Scengen rules, its clear that I have to apply at Greek Embassy, London. Now the thing is before this I have applied for Schengen visa 4 times and all of them is in with French Embassy, but in this case there is no way I can apply with them, as judging by number of days it is very clear that Greece is my main destination.

Now my question is, does anybody has any idea on the methods and ways about getting a schengen Visa from Greek Embassy. I have read some pretty nasty stories about Greek Embassy Geneva before, and I have my doubts whether its same in here.

Any first hand/2nd hand experince of dealing with Greek embassy London is most welcome.
Thanks
