The price for 2 croissants is 2 cappuccinos for €6.00, it seems excessive to me (croissant sold as filled with jam, instead it was empty), luckily it was S. ONOFRIO (TE) if it was Teramo city, I would have had to take out a mortgage for 2 breakfasts.
I usually stop when I go to Teramo and I don't take the highway. It's located in the middle of the route. The coffee is good, still costing 1 euro, the rustic cake that the owner makes at home, various types of sandwiches, etc. Friendly and easy-going. There's also a petrol pump.
