It is very over priced for what the food is. There aren't many options to get these type of street eats all in one place but if the food isn't fresh or the stall is not consistently preparing new batches of food then it's just not as fresh and loses its appeal.
It actually felt like Taiwan with the crowds there, depending on how well you do in big busy crowds you might hate/like it.
I got the fried noodle bun, some skewers and a variety of egg rolls. I did not get a chance to get the stinky tofu as the line was so long they ran out for a moment.
So I recommend going early to avoid the crowds (if possible) and to park away from the event as Asian drivers in high volumes is never a fun place to operate a vehicle. (It's ok I'm Asian and fortunately learned to drive in a small town)
