Saw Zookz while driving around. Stop in for a sandwich, had no idea what to expect. Each sandwich comes with a side: chickpea salad, potato salad or kale salad. Got the Kale and the Chickpea, both were pretty good. Would recommend the chickpea. Got the number 10 and 20. $18
My take on it was just a different version of a grilled cheese. The contraption they use is pretty cool. I'm glad they didn't use the basic white bread I remember having when I was young. It's a bit of an upgrade I'd say.
Would I come back? Probably not, when I think of a good sandwich, the bread is my deal breaker. Cool concept if you love grilled cheeses. Just didn't tickle my fancy.
