Stevi B's isn't a good place to go for a romantic evening, obviously, and I probably wouldn't even go there to try to carry on a grown-up conversation, since you won't be able to hear your dining companion over the 5 billion small children that will inevitably be running all over the restaurant unsupervised.
That said, if you want to take your family out and show the kids a good time, this is a safe, clean place to go for cheap food and cheap laughs. The pizza buffet features the usual suspects like cheese and pepperoni, along with more bizarre selections like macaroni and cheese pizza. There's a small salad and pasta bar, along with a pretty good dessert selection. Stevi's also has a pretty big arcade for the kids and a decent array of prizes for the arcade gamers to win.
We only had one complaint - the place was so busy that all the tables were full, but the staff were still letting people pay and come in the restaurant. They couldn't make pizzas fast enough to catch up, so people were stealing tables and stealing food! It felt a little like we were at a feeding trough. Maybe a waiting line would've helped.
