Driving from Ithaca to Bethesda, we anticipated passing Harrisburg around dinner time, and a hundred miles ahead, Gabriella showed up on my nav system -- I knew it was around Harrisburg and reasoned it was a real restaurant, on the route, near a city, and hence likely a cut above normal travel fare. How lucky we were! This was a real find. We had a great meal, attentive service, delicious gnochi, nice atmosphere, accommodating to our need to get back on the road, amazing for a place right off the highway. We'll be making this trip frequently, and Gabriella is in our plans. In short, you don't have to live near Harrisburg to benefit from this gem.
Pros: En route, DC to upstate NY
Cons: No credit cards, bring your checkbook or cash . . .
