The story
In the village of Lostallo, at the southern edge of the Grisons, the Rosa family has been welcoming guests for three generations. Today, chef-patron Alan Rosa leads the kitchen at Groven, a restaurant that earned a Michelin Recommended distinction for the 2026 guide.
The menu is grounded in classic cuisine, built on fresh local ingredients and seasonal produce. Game plays a prominent role — venison saddle, served with thoughtful accompaniments like melon, glassed chestnuts and a well-judged sauce, draws particular praise. A house specialty, bollito misto, is prepared with the same exacting precision, elevated by the accompanying sauces. The cheese selection is equally considered, with a dedicated room offering an array of local varieties.
Groven’s wine list is deep and curated, drawing from Swiss and international labels. The sommelier is on hand to guide pairings, and the restaurant’s enoteca in San Bernardino — a walk-only wine bar — extends the same philosophy in a more casual setting.
Alan Rosa inherited the kitchen from his father Giacomo and grandmother Maria, who ran the restaurant before him. His style remains close to tradition but with a creative, personal touch — a signature that has earned him a reputation well beyond the valley. The dining room is warm and unfussy, with service that feels both professional and familial.
For those looking to linger, the restaurant also offers simple, comfortable rooms, making it a natural stop for travelers exploring the Grisons’ southern valleys. Each meal is a reflection of the land — straightforward on the surface, nuanced underneath.
