There is a new book store on Main Street called Greenrow Books that specializes in children's books and cookbooks.
Amanda Yeager has a short profile in the Sun, and she notes that Greenrow will run a food-based book club, partnering with the Rumor Mill. The club will meet at the restaurant where chef Matt Milani will riff off the book for appetizers and drinks. That's definitely something to check out -- both cookbooks and the book club.
If you want to shop locally, check out last year's series about local shopping -- both food and non-food gift ideas. The Boulder mens store closed, but I think the other options are still good.
