My experiences: Antica Corona Reale da Renzo. (Cervere) - was excellent several years ago. Polished versions of trad dishes. Locanda dell'Arco, Cissone Roots Piedmontese cooking in a beautiful room in the Alta Langa, a few minutes from Dogliani. Terrific cellar including some older bottles, and the proprietor really knows his wines. Agriturismo also, including some newer rooms. Osteria dell’ Arco (Alba) - Slow Food outpost. Ate there in April, thought it was excellent. Good list. Boccondivino (Bra) - Slow Food company canteen, essentially; was excellent several years ago. And if you haven't tried it, La Coccinella in Serravalle Langhe is outstanding. It's in the Alta Langa, not far from Dogliani. Three brothers run both kitchen and the dining room; terrific food (very flavorful but not heavy), with a wine list that gets better every time I go. Two simple rooms upstairs for agriturismo. For the definitive Bollito Misto, Ristorante Moderno in Carru, which bills itself as 'La Patria di Bollito Misto.'
