"Good Italian food with reasonable prices for a high mountain tourist destination. Unfortunately, this restaurant is flawed by mediocre service. We visited this restaurant twice. The first time, the serving team seemed haggard and understaffed but service was passable and friendly. However, we noted the staff had no tolerance for guest requests: multiple people in ear shot of us requested table changes or menu substations and were universally denied. On our second visit, it was clear the staff forgot to put in our entree order we waited over an hour for a vegetable pizza (with several gentle reminders from us) while tables seated long after our arrival received their orders all around us. The best we got in explanation was sorry we are busy tonight. Outdoor seating is available, but in high demand. Take out pizza is on offer (probably the smartest option given the above mentioned issues with service). Generous desert options. Good kids menu (although with pizza on offer it 's hard to go wrong for kids). There was excellent live music on the terrace during our weekend visit. Wine selection was good, beer was all bottled, minimal mixed drink offerings. The restaurant is attached to a bar of the same name. The bar has a simpler but similar menu. However, we learned that the bar is not open during the summer season. That was not immediately obvious from their website. Bottom line: I want Da Sina to be my go to family restaurant in Wengen, but it is marred by mediocre service and an inability to cater to its customers..."
