I am meeting someone for lunch on Saturday in the Harrisburg area. We are both driving 1-1/2 hours to meet in the middle, he from the north on I-81 and me from the south from US-15. I've seen some recs for Harrisburg restaurants, though they mostly sound like they are in the city. Since neither of us know the area, I was wondering if there is a casual, inexpensive, but chow worthy place where we could linger somwhere easily accessed from the highway. Any ideas?
