where to have a quick, early dinner near 30th St train station?

Hi, Philly Moms --

I'm meeting my daughter, two of her college friends and my college roommate in Philly tomorrow to attend another friend's piano recital. We'd like to have a quick dinner around 5 pm near the 30th Street train station. I'd appreciate your suggestions, other than the usual suspects -- i.e., fast casual chain restaurants.

Thanks!
