What's up with 10 Rittenhouse, the luxury high-rise condo nearing completion at 18th and Sansom Streets?

The Illadelph reported this morning that its restaurant space will be at street level at the corner and also speculated about the occupant.

I can confirm that Serafina, the Manhattan Theater District Italian, is in negotiations. While developers are not talking, a rep for the restaurant noted that negotiations were ongoing. The concept would be similar to the Serafina at 55th and Broadway, whose lively, Fellini-esque atmosphere was conjured by David Rockwell.

Also in the running for the space is restaurateur Todd English, whose holdings include his Boston-area flagship Olives.

Stay tuned.
