Short leash is quite unique, but the novelty wears off quick.
I've been to the food truck twice and the restaurant a couple times as well. I liked it the first time, but it was all about the novelty factor. Additionally all of their items are priced quite high. for a regular dog, it was 9-10 bucks. I would be okay with it if it were a substantial portion. Unfortunately, it leaves me hungry.
Overall, a cool concept, but not worth the value. It's good if you want to try something new, and don't care about bang for your buck.
