I had lunch at Gran Scala during a trip to the lake. A no-frills place where you can breathe an authentic atmosphere. Very friendly staff, the waiters speak fluent English, Italian, French and German and are very kind. The cuisine is tasty, mountain dishes with local products, well cooked and with generous portions. The price for the area and the offer is more than fair; two first courses, a second course, a dessert and water around €40. I recommend stopping if you are in the area and want to eat.
