We've been here twice as a family. The first time we came, it was a "meh" experience, but decided to come back a couple of months later in hopes that it was a one-off bad experience.
Unfortunately, the food is bland - nothing appears to have salt in it. Mashed potatoes contained absolutely no seasoning whatsoever, the fries were seriously undercooked (borderline raw) and for what you get, it seems very overpriced. Burgers were fine, but definitely nothing to rave about.
I truly wish this place had better food, because even if service was a bit spotty, I would be willing to pay extra for decent comfort food and for the fun 1950's diner ambience. Unfortunately, our experience at Jukebox left a little something to be desired.
