Gave this a try at this years Ex. I had the Juicy Oink combo with chips.
This is basically a sesame seed hamburger bun with a depression in the middle as the base. Its then topped off with various fillings.
The Oink had a tablespoon of pulled pork topped off with a small pork dumpling. I dug deep to try and find any sign of pork belly or pork skin (as advertised) but couldn't see or taste any. More bun than ingredients. Virtually impossible to eat as 'street food' without loosing what little filling there is onto the sidewalk. Overall taste was uninspiring. Sadly the prepackaged chips tasted better.
