a brewpub for families is like mixing oil and water, in my personal opinion. people with families don't go out to drink good beer and eat good food with their kids. they go somewhere that the kids will enjoy. when the couple goes out alone, they are going to go out for a nice dinner at a nice restaurant.
a brewpub is going to attract younger, single people. old people drink bud light, keystone and anything that tastes like water and goes down easy.
