From inauspicious beginnings as a cake wholesaler in 2001 has arisen a giant of the dessert world. The wholesale business, directed toward restaurants and hotels, expanded rapidly, necessitating a move to a larger space and eventually begetting a boutique cake shop on the Upper East Side in 2004. After opening a second location in the Plaza Food Hall in 2012, Lady M opened this shop in 2013, and has seen business continue to boom. The Japanese chain now spans international borders to Singapore, in a demonstration of the power of a quality product. The specialties here are the Lady M Mille Crepes, cakes made by stacking alternating layers of ultra-thin crepes and sweet light pastry cream. The vanilla Mille-Feuille is a classic; the green tea rendition demonstrates the signature blending of French and Japanese styles. But the roster goes deeper than its star player: the cheesecake won New York Magazine's best cheesecake award in 2006, the coronne du chocolat was featured as one of the chicest chocolate cakes in the city by Vogue Magazine. It is a treasure trove for the sweet-toothed. The simple, airy, elegant architecture of the space, with only a few tables to sit at, perfectly enhances the experience.
