My father is coming in from way out of town for a meeting and we want to meet up for dinner. He will be here only for today and has somewhat small time window of ~3:30 til his Amtrak leaves Penn at 8:15, so an early dinner would be necessary. His meeting will be near 31st and & Park, so I'm looking for something within a reasonable distance of there and Penn Station. It should not be too loud as we will want to catch up and not overly expensive. We are both adventurous eaters. Any recommendations?
Please help! I rarely eat in that vicinity except for Shake Shack and Kalustyan's.
