If you had followed Ryan Nelson’s career from the beginning, you might have predicted the scene: Just 10 days after he opened Late Harvest Kitchen in the former Smith & Hawken storefront near The Fashion Mall, Nelson strolled from table to table in the packed, candlelit dining room of his first solo enterprise, talking to customers with the ease of a seasoned restaurant professional. But in many ways, he was still the guy from Minneapolis, the onetime English major and avid hockey fan a tad uncomfortable in his chef’s whites, humbly hoping you enjoyed the food he had cooked for you. Only now he was not answering to the corporate offices of The Oceanaire Seafood Room, where he established himself as both team player and rising star, garnering an invitation to cook at the revered James Beard House in New York City at age 26.
