Frasca Hospitality Group is on a roll. Last week, Michelin named one of the company’s Denver restaurants, Tavernetta, to its Bib Gourmand category, which are restaurants that it believes offer a meal of good quality at a good value. Today, the company, which also owns Frasca Food and Wine and Pizzeria Alberico, both in Boulder, said it will open a new Italian concept dubbed Osteria Alberico at 3455 S.
