Great Food and Wine Experience in the Khaoyai Region If you want a relaxing few days off in great green country with clean air, cool outdoors and good food plus the best vineyard experience, look no further than PB Valley Vineyard and Winery in the Khaoyai area of Nakhon Ratchasima! Come during the flower season too and the harvest season if you want to try a hand at making and stomping on grapes for wine! The food is great and prices reasonable with fairly large portions. A good mix of western and local Thai but do give the chef special a try, it is always changing. #1stbd
