I lived in Italy for a bit, and we went to Euno because the sign was identical to the sign of my favorite restaurant in Arezzo. Granted, this is a superficial reason to go to a restaurant, but I had to figure out some way to start choosing restaurants to go to in my new neighborhood, seemed as good as any. The restaurant was fantastico. The upstairs was full, so we had the downstairs all to ourselves. The charming waiters sat us by the fireplace in the amazing brick basement room. If you have a choice, sit down there, the cielings and wine wall add to the experience, to be sure.
Pros: The basement, the FOOD, the waiters if you get the ones we did
Cons: Parking, obviously (don't bring your car to the North End! Or expect to park in a garage!)
