Kid friendly for dinner around 5pm on a Saturday?

Yes

Yes I took my kids.. we had a blast

There's also an outside patio area that may work for you if the weather is tolerable.

Yes kid friendly. Had dinner and i got carded at the door though many families there having dinner at 6:30

There is live music and I imagine it gets a little wild, maybe older kids. Might be a little much for small children
