There are five restaurants in the municipality, in three different places. In the main village is the Antico Ristorante Drago, on via Roma, the only business in Oltre il Colle on the regional register of historic businesses, run by the same family since 1870. Zambla Alta has three: the Miramonti on the provincial road and, on via Fezzoli, the Quattro Cime and the Neve, less than 200 metres apart. At the Passo di Zambla is Al Trapper, with its picnic park and barbecues.
The cooking is that of the Bergamo mountains: the published menus keep returning to casoncelli, Bergamo-style polenta and polenta taragna with mushrooms, melted cheese or game, venison and roe deer, and the valley's cured meats and cheeses. Three of the five also make pizza: the Quattro Cime, the Neve, which serves it in the evening, and Al Trapper, in a wood-fired oven.
None of them publishes opening hours. Three have a website, the Quattro Cime and the Neve with menus and prices, Al Trapper with a menu without prices; for the Drago and the Miramonti there are only phone numbers. Call before you drive up, and Al Trapper expressly asks you to book. The entries report what the restaurants themselves, the council, the Pro Loco, the Region and the local press say, with dates, and not review portals.
