So I'm about to leave for a very-impromptu weekend trip to Philadelphia, where I haven't been in about 10 years despite being two hours away. I'm looking for a place to have dinner tonight, and maybe brunch tomorrow if the hotel offering turns out not to be free. (I can't turn down a free brunch.) Here's what I'm looking for: good (obviously), reasonably with-it food; hip neighborhood; entrees more like $20 than $30. Cuisine is not important, though if Philly is as happening as everybody says it is, I bet a lot of the places that meet my specifications are Thai, and I've had just about enough of that at home, thank you very much.
I don't know about Internet access where I'm going, but I'm sure I'll at least be able to read your responses (thanks, work-issued BlackBerry), so your help is much appreciated.
