Always on the lookout for the hottest restaurants, ingredients and flavors, TravelsinTaste.com recently had the opportunity to chat with its resident garden fresh flavors expert Executive Chef Mark Sandoval of Wolfgang Puck's Postrio in the Venetian Resort Hotel Casino. Having worked at such notable restaurants as the award-winning Carneros, located at The Lodge at Sonoma, The Harmony Club on the Plaza, also in Sonoma, and Joel Robuchon's The Mansion in Las Vegas, Chef Sandoval is known for his focus on freshness. In fact, he even has his own garden and has been known to share the fruits of his harvest with his restaurant guests. Because of his love for garden-fresh produce, Chef Sandoval is always on the lookout for new, unique ingredients for his menus. When we want to know about new dining trends in Vegas, therefore, he's the first person we ask. And ask we did -- about the latest trend he's seeing in off-the-Strip dining: the gourmet food truck.
