Korat BBQ festival 2014
It appears that the BBQ festival this year in Nakhon Ratchasima will be from 12 to 16 December 2014. It is normally organised by the Korat Chamber of commerce, with a theme of Cowbow and Indians, lots of food, music and others. There is a large selection of OTOP product and it is during the best period of the year. So you can also enjoy beer and BBQ at the same time.
