Over the course of its three-year run out of a spartan former biker bar, Rebel Restaurant received not one but two three-star reviews from The Denver Post. Owners and chefs Bo Porytko and Dan Lasiy changed their menu often but became known for pierogies and whole hog’s head dinners, among other offbeat plates. So when news came that the subversive — in style and substance — spot at the edge of RiNo was closing last August, fans were understandably heartbroken.
