Basque-country chef Michel Moutrousteguy offers a Mapuche-infused French menu that's well worth the trip to Termas Peumayén (for the food, not the service), 32km east of Pucón, even if you don't plan on getting wet. It's meat heavy (wild rabbit, beef tongue pot au feu, beef bourguignonne), fiercely local and seasonal, and the region's gourmet destination for foodies.
A three-course menu plus entrance to the hot springs runs CH$27,500. Peumayén is reachable by car or five times daily from Pucón with Fer Bus (CH$1500).
