sacramento - kids
It really depends on the ages of the kids and how well-behaved they are. Unless they are babes-in-arms, most California kids seem to like sushi and dim sum as they can pick and choose from a lot of small plates. Tapas places are also good. As are places with noodles or Mexican food. You really have a lot of places to choose from in Sac.
The key is to avoid places that have a long wait for a table, that take more than an hour or so to eat in, and romantic places where kids might upset the other guests. Kids are generally fine as long as they don't have to wait too long for anything.
