Robert Irvine returns to Paterson, N.J., to check on one of his most-unique renovations, Paul's Bar and Bowling. When Robert first visited Paul's in 2014, the family business hadn't been updated in decades.

Now he's back to see if Paul has been able to keep up the improvements and ensure success for years to come.
