“The Tourism Authority of Thailand (TAT) is debuting Rumble in DC, an incredible Muay Thai tournament, on Tuesday, September 18th from 6 pm to 10 pm at the Woodrow Wilson Plaza at the Ronald Reagan Building.

This free event will feature a traditional Muay Thai match, and guests will also have the chance to witness a Wai Kru performance (a Thai ritual performed before the match to show respect), enjoy delicious Thai cuisine from local vendors, pamper themselves with a Thai massage and even get a temporary Thai tattoo at the TAT booth at the event.

Please join the Tourism Authority of Thailand and experience the magic of Thai culture and traditions.”
