Joe Bova and Jeff Steinberg, formerly in the entertainment industry and most recently the men behind the chocolate chip cookies at DMK, are expanding the biz. In late January, they plan to open Cookie Bar, a bakery in Lincoln Park that specializes in . . . well, cookies. Think potato-chip chocolate chip and at least a dozen different flavors, such as oatmeal-mango-chile-macadamia. The “retro aesthetic” spot with a barlike atmo will cover a lot of ground with coffees and dairy- and gluten-free baked goods as well. Still and all, six types of chocolate chip cookies will be baked daily because, Steinberg says, they’re “everyone’s favorite.” 2475 N. Lincoln Ave.; 773-348-0300.
