Absolutely terrible.
Having been to the location in Milpitas CA and Jillians in Charlotte, NC. i had high hopes. Its nice to be able to act like an overgrown child without having to contend with kids running around everything. (Both of the other places didn't let underage kids in after 5pm.)
Yet I come here, and its like I was walking into a Chuck E Cheese with beer. Kids running around all over the place, playing on all the stuff I wanted to play. Finally get to play whatever, and some parent is standing over your shoulder because their kid wants in. I don't hate kids or anything, but damn. The food and drinks absolutely cannot make up for how much the place sucks.
Their game selection is also wanting, but I've said enough.
