Arrivederci is one of those little nice family owned restaurants that people keep kvetching the valley doesn't have enough of. While it's not the best Italian food in Scottsdale, it serves up some wonderful meals at reasonable prices.
For me, it brings back memories of many little whole-in-the-wall Italian restaurants my family and I used to visit when I was growing up in Chicago and Cleveland. As others have said, the decor is awful but easy to look past. The "rustic" wall paper and wine racks probably had an authentic old school feeling 20 years ago, but the dining room could drastically use a 21st century update. The Ferrari parked outside is cool for a quick glance, but really just serves as a fairly pointless "wow" device.
The food tastes fresh, the sauces are good but not overpowering to the dishes, and the service is great. The only thing I don't recommend is the complimentary liquor shots we received at the end of our meal. Awful. The server said it would help with digestion. It left me feeling like I was suffering from indigestion.
