My sisters and I would like to take our mother to a tea room for her 50th birthday. We live just outside of Philadelphia and are thinking about the Cassatt Tea Room at the Rittenhouse Hotel. We would like to go somewhere elegant and fun. We have never been to a tea room and really want to make this special. Please give me some feedback if you know of any other great tea rooms in the area or have any information on Cassatt. Thanks so much!
