Been there about two weeks ago. IMHO the quality of the girls has really went down hill in the last 1 1/2 years. Happy World used to have some lookers, but now the best they have in my opinion is a 7 on my scale.
Happy World is a Soapy Massage, it also has karokee, and a disco tech in the same building.
Is it worth going to? If it were me I would drive another 5 minutes down the road to Galaxy Bang Saen. Alot better quality of girls for the same price. IMHO
