This right here is Savarona, a new Midtown Turkish restaurant that opened after a two month long delay last week. The chef here is Tevfik Alparslan, who has worked at La Tour d’Argent and Gordon Ramsay. His food is decidedly upscale, but probably something residents of Sutton Place haven't seen before in the area. The pared down design comes from David Howell, someone known more for his retail concepts than restaurant spaces.
As for the early word, there really isn't any besides one Citysearch user review citing the food and service as uneven. We'll have to wait for those Midtown East residents to try it out and get on the Chowhound. Further reading here and here.
