One current big difference between pubs and restaurants is that you can walk around the pub with your drink in hand. Maybe not a big deal at most pubs, most look like restaurants with most patrons seated, servers know who they IDed, and generally where they are. But consider a place like the Sticky Wicket/Games Room/Clubhouse on a busy Friday afternoon/dinner time. I could see some cases there where the servers lose track of which people are underagers, and which "kids" came in with what parents. Suddenly it's not as easy to curb underage drinking. Also, can an 18-year-old come in with brother/sister/friends that are 19+, or must it be "parents"? I don't think they could really discriminate against any guardian, and this could very well be an older sibling, or an adult that would not normally be possible to be a biological parent (ie. they are 22, and the guardian of a 17-year-old).
Again, not hard to supervise in most places, but busy Fridays etc., I could see all kinds of problems in some places.
Now, what do you do at 10pm or 11pm or whenever the minors cut-off is? How do you ID 300 people inside Bard and Banker without the underagers shifting around to avoid the ID check?
I truly think that most busy pub owners would not think this is worth the trouble. You make most of your money on booze, so while not letting in adults with kids may lose you a tiny bit of business, the fact is, the capacity you loose to allowing two kids in that won't drink, is not worth the bother, when you add that to the enforcement headaches. Every underager found drinking in your bar will get you at least a $1000 fine, and every underager found there past the minors cut-off will get you at least a $2000 fine. These escalate with further infractions.
Again, it all sounds fine when a couple comes in with two 8-year-old kids at noon for lunch. It gets very difficult at 8pm when your bar is full of 18 year olds mixing with 19s and 25s and everyone is moving around.
Many, many pubs (I'll probably say over 75% of them) also have self-serve lottery terminals (both keno/50-50/poker machines as well as pull-tab machines). Restaurants don't. The idea being, of course, everyone in the pub is 19+ and can gamble. How do pubs police that if they let kids in? I'll guess if up to pub owners, to be kid-friendly and lose the machines, or be no-kids and keep the terminals, they will go with keeping the terminals. The government also likes this lottery revenue too, from pubs. I'm sure they would not like to see hundreds of these machines turned in.
On the other ideas, booze-only orders in restaurants sounds fine to me.
