I'm heading to Philly for one night and am looking for good options for a solo diner. I'll be staying in center city, but am willing to head to the old city for dinner. I've been reading good things about Zahav and Dandelion. Are either of those spots suitable for a solo diner? Any other suggestions? I've eaten at Alma de Cuba on past trips and enjoyed the meal and atmosphere. My budget is about $75.
Also, I'll be up near Penn the following day. I hear that there are some food carts worth checking out. Which ones stand out?
