I bought the 1/3 lb version for $6.99.
The construction of the sandwich makes for a pretty messy eating process. The chips and pickles were situated on the very bottom and formed an uneven base for the lettuce and tomatoes (wet ingredients that slid too and fro atop the chips). On top of this Jenga-like Slip & Slide were the heavier beef patty and split hot dog. Additionally, the hot dog only covered one side of the burger. Basically, you might want to eat this burger upside down and hope for the best.
True to the concept, it did indeed feel like eating a burger, a hot dog, and potato chips all-in-one. But that's the problem; it felt like I was trying to cram all of the above down my pie hole before all the various ingredient fell out in a very un-summer-like fashion.
