Over the past couple of years, Central and South American food has become a hot style as young chefs looked even farther south of the border for inspiration. But Denver has had its own inspirational Peruvian restaurant for years. Behind an unassuming downtown storefront is Los Cabos II, a combination restaurant/cultural center that's decorated with native art (and a giant stuffed llama) and serves authentic Peruvian peasant food to all comers. These days the crowd is just as likely to consist of adventurous office workers looking for a hit of bistek a la pobre, papas a la huancaina and a pisco sour as it is of displaced Peruvians hungry for a taste of home. Fortunately, the sudden attention placed on Peruvian cuisine has only made Los Cabos better, with a recent overhaul of both the space and the menu.
