I can't believe no one has mentioned La Cigale and Lenotre??!! Hazelnut and choc, whiteforest, choc fudge etc etc just divine.

In my humble opinion Patissierie Suisse and Opera don't make good cakes, they taste artificial.

Bateel does a good triple choc-cake (dark,milk and white) but deceptively calls it 'victoria' cake.

Apparently Fauchon also is good, though I don't have a personal recommendation.

Aisha-Taweela- I definitely will be heading to Ma Maison for comparision purposes only ofcourse!
