Friday night and there are children (5-7 year olds!) running around, we ask the bartenders about this, and they say there is nothing they can do- it's up to the owners.
Obviously it's the parent's extremely bad decision (plus lack of enforcement? aren't there door guys to check id?) , but just beware- you could come in for an after work drink, and feel like you are in the middle of a daycare. And no one will care (except you!).
