Traffic is extra heavy by the river but if you're only going to the winery gps will take you around the traffic jam
We were at the rooftop with a 7 y/o and also saw a bunch of people there with even younger kids. This was during the day. I'm not sure how it is in the evenings.
Traffic is always heavy, tourist area. Rooftop is family friendly. Live music is very pleasant. Southern Red is my best. Enjoy!
