In a lot of ways, Rioja is a dream restaurant -- the sort that chefs fantasize about, with a great location, a solid crew of experienced veterans and a menu that allows that crew to improvise upon favorite dishes night after night. For chef Jennifer Jasinski, that means doing pasta -- lots of pasta. Lots of beautifully executed, expertly balanced plates of handmade pasta presented daily to a crowd that seems to love them all without reservation. From the fat, pot-bellied pansoti stuffed with cheese and roasted acorn squash to cannelloni in black-truffle sauce and the tiny duck raviolini in the kitchen's wonderful consommé, Chef Jen has much to be proud of. And much work to do every day to fill the demand for the best pasta in Denver.
