I had occasion to be in the area of Lebanon, PA today and stumbled on a place called Cahill's Fish & Chips at 7 North 9th St. (Rte. 72 heading north). The had a limited fare but it was of excellent quality and simply served on plastic plates. The fish & chips came as a platter with a vegatable and either applesauce or cole slaw for $8.95. It was more than enough food - I couldn't finish my chips. The lady that owned it was very nice and made us feel welcome. It is definitely not fancy but the food was quite good.
