Well, there are lots of theaters an easy taxi away.... not the movie ones, but the types that have plays. RS is shops and restaurants.
Personally, I like it down where I work...... in Old City, around 5th and Market streets.
I don't know if I would call it "romantic" but there sure is a LOT to see and do..... great places to get dessert, a few places to shop, and historical sites. The side streets are where the best stuff is found.
RS area is more upscale than most, but I prefer not to be quite so upscale. Old city is just a little more "earthy"...

..but more fun for me, and I'm almost 44.
