I've been to a couple of there ones that where tolerable. If they are big enough to let the kids spread out and had enough decent games to play you can overlook the terrible pizza.
There used to be one in Lancaster that had an awesome collection of old video games. An original PacMan, Space Invaders, and other classics because the owners where too cheap to replace them and to stupid to realize they where collector pieces.. The geek group from the office would sometimes go there over lunch when we knew the kids where in school.
