San Carlos de Bariloche is my first town to visit in Argentina where is well known for local tourists especially for high school as the annual outing. From there, you can find numbers of beautiful lakes, Mountain skilling in the winter (with cable car if course). To enjoy the food (steak is high recommended) & drinks along the main street. Eventhough it's a small town, you can find a lot chocolate shops, restaurants, small hotels with Europe feeling all year round.
