You can't get fresher than Right by Nature, a natural foods supermarket that was to open at 8 this morning at the Cork Factory complex at Smallman and 23rd streets in the Strip District. The gleaming 22,000-square-foot space is owned by Bob Stone, a Lawrenceville native who started out working in produce in the Strip and has been a produce buyer for national chain stores for two-plus decades before returning here. This store, which will sell its own baked goods and prepared foods, offers free parking in the adjacent garage, even curbside pick-up. Mr. Stone says prices are surprisingly low for healthy fare. A portion of daily sales will be given to seven area charities in a "7 Days of Giving" promotion following the opening.
