I'm looking for a spot for dinner on an early Saturday evening (say 6pm) with my wife and a (reasonably) well-behaved 3-year old. We'll be staying at the Mariott right at City Hall and are open to a longer walk or a short cab. BYOB would be great (we don't get that chance in NYC), and thinking something reasonably nice. A number of options pop up in the search (e.g., Matyson, Osteria, Cochon, Melograno and many more) but I can't tell what works with the little guy. Food isn't the issue, as he eats, but we'd probably want a reservation to avoid boredom from a long wait and wouldn't want a place where he would be out of place or bother anyone (i.e., not a quiet date place where any noise is too much).
Also, how would a 3-year old be viewed at a nicer craft beer bar in Philly? Say Monk's Cafe. Again, we are talking early or even during the day, quiet and not bothering anyone. It works in some places here in NYC and not others.
