We stayed in Bariloche for nearly two weeks and ate at a number of restaurants. In our party of 3, we concurred that Aashi was the best. Healthy food (can even prepare it as vegan, if you wish), that is incredibly tasty. Although the menu only has about 5 main dishes, including pizza and burger, each one was really good. And the smoothies are to die for. Just be aware that Aashi only serves lunch, and that starts around 1 p.m. It is located outside of town, on the Circuito Chico. It is just a 4-minute walk from where you rent bikes (near the round-about where the Circuito begins and ends). When coming from town, you take the left prong at that roundabout, and it is on the right with a large sign that says Aashi. Enjoy!
