Half Day of Family Fun0
You should be able to hit two wineries and enjoy a nice lunch before you have to head on down the road.
First pick which side of the Paso Robles appellation you want to explore: east-side or west-side.
The Berry Hill Bistro is located in Paso Robles on the town square and park. It is also centrally located between the two wine trail and freeways for travel convenience.
Fun for the kids:
Let the kids run about the park after lunch and take them to Cold Stone Creamery for dessert. They will hopefully reward you with some quiet-time when the sugar wears off and the road lulls them to dreamland!
