We're headed to SF for the weekend with two boys (7 and 4). We're taking in Fleet Week, Zeum and the Exploratorium and are staying near Union Square. I'm looking for a convenient (walking distance) sit down dinner destination Saturday night. Not necessarily looking for a "Chowhound worthy" spot this time around - just something decent with kid-friendly food. For us, "kid-friendly" means pizza, chicken strips, quesadillas, etc. Any recommendations? Thanks!
