"Haute" Ethnic Cusine - does it exist? What is the closest we get?
Ilili purports itself to be haute Lebanese, though it elevates Lebanese food by using fusion techniques and ingredients a la Tabla.
Maybe it's me, but I have a hard time defining a "haute" version of the cuisines you've listed. Is the haute-ness of a place defined by its ambience? Because there are plenty of beautiful Maghrebi restaurants. Is it price? Because Merkato 55 has certainly redefined the price point for African food. Plating? Technique?
