Need some recommendations in Rittenhouse Square or Olde City. We are staing at Rittenhouse Hotel and having 8:00 dinner at Fork. Would like to head out around 5 for some good drinks and cool ambience. We are in young 40's- like high quality drinks and classy ambience, but also like to be at a happening place with a lot of people. Some ideas are one of the bars on Ritt. Square, Alma De Cuba, Buddakan, Continental, Brasserie Perrier. Would you recommend any of these, ro somewhere else?
