There is a meet up of 5th Gens in Clifton at Riverside Bar &Grill
2 South Parkway
Clifton, N.J.
It's a car club that I'm joining. The Smokin Bowties. I believe there is a one time $25 entrance fee.

Otherwise there is always the Whiskey Cafe in Lyndhurst every Saturday night. It's usually a good show.
