Cart-Driver will swing open its doors at 4 p.m. this afternoon; it's helmed by chef Kelly Whitaker, whose Boulder joint, Pizzeria Basta, has already secured a solid reputation of its own. Expect blistered pizzas from that oven, as well as a range of small plates, oysters and what partner Andrew Birkholz refers to as "simple fare" in the manner of an Italian "street food vendor." The eatery also has a liquor license, so drinks will be available to complement that fare.About the name? Completely devoid of ampersands, Cart-Driver refers to the traditional Italian carrettiera, who delivered produce in a horse-drawn cart and offered fresh-cooked dishes along the way. Like that carrettiera, Cart-Driver will also offer a small range of prepared foods for customers who want a fresh-cooked meal to take home. Not much bigger than a horse cart, the 640 square-foot space will have regular business hours of 5 to 11 p.m. on Tuesday, Wednesday, Thursday and Sunday, and 5 p.m.-midnight on Friday and Saturday.
