Think there's no such thing as a free lunch? Think again. On weekends at Whole Foods Market in Cherry Creek, you can watch groceryland's most eclectic, entertaining crowd while snacking on enough bite-sized organic niblets to fill you up -- and then some. On any given Saturday, you'll find trays of sliced fruit, cups of deli delights or chunks of kalamata-laced bread, and to top it off, you're always free to sample from that Mediterranean Mecca known to shoppers as the Olive Bar. The only downside to this lovely Saturday-morning excursion is that the parking can get a trifle hairy, but at least you can build up your appetite while waiting for that gas-guzzling Mercedes SUV to back out.
