The flavor was very similar to Vanilla Coke (ohhhhh man, I could go for a Vanilla Coke right now. With my wasabi peas.) and it lasted about 10 seconds. Bubble blowing was a bit strenuous.
The most exciting part for me were these Thai comics on the wrappers. The jokes (as you would expect) are based exclusively on Thai culture and Thai language. Poor Hong had to wring the jokes dry in order to explain them to me, and even then I only really understood one of them!
