I don't know anything about this type of food, but the festival looks like a good place to explore the different varieties. I can see the crowds. I agree with you that the food not covered posed a health risk, especially if bugs and flying insects settled on it. Definitely, all food should be covered with a see through container so that people can still see what they are buying. Also, some of the food vendors weren't wearing gloves nor hair garments. This is definitely a safety issue.
Thanks so much for sharing your visit. The food did look delicious.
