Have booked in to the Rittenhouse hotel for a Saturday in early December with the dear lady wife. I am looking for a romantic informal restaurant, that serves lighter food (New American? Italian / French)...Recent postings on Brasserie Perrier not to good. Rouge is OK. Want to escape Rittenhouse - thus no to Lacrois. Not a great fan of Stephen Star restaurants - although may go to Alma de Cuba for a mohito to start the night off. Thought about 20 Manning - would welcome any other suggestions - BYO is OK. Must be walking distance of Rittenhouse Sq.
