This Boulder bistro creates French Provençal cuisine in the mountains of Colorado. Seating includes a long bar and two rows of tables with white cloths, bathed in natural light from the windows. Clusters of abstract, tapering pendant lamps cast a golden glow. This foodie-style place has seasonal menus paired with French and Italian wines. The Mateo Burger, a signature dish, consists of Colorado sirloin, caramelized onion, house-cut frites, and herb aioli. Other options include French onion soup, chicken frites, and duck confit. Mateo regularly hosts events, such as wine dinners and an annual summer dinner at a farm.
