A new bookstore concept is coming to Midtown. Entrepreneur Kevin Standfield and a partner are turning a former office space into a used bookstore and wine bar at 1330 21st St. The establishment will also sell cheese, beer, dessert and coffee. "My two favorite things in the world are to sip port and read a book," Standfield said. "I like the idea of our customers being able to sit down and hang out and read a book." To come up with a name, Standfield stuck with a theme he likes. He's calling it Book Monkey, like the Yogurt Monkey shop he and a partner opened on Fair Oaks Boulevard. "I'm in a monkey thing right now. I don't know why," he said. Boxes of books sat under plastic Wednesday
