Cup O' Joe is a coffee shop that Francine and Roger stop at in "The Dentist's Wife".
When Roger sets out to impress socialite Meredith Fields, two different personas fall flat. After his second failure, he comes to feel as if he has no identity of his own and withdraws to the trunk of Francine's car. She convinces him to put on a poncho and a mop wig to sit up front in the car with her. They stop for coffee at Cup O' Joe, where he finds a flier for Meredith's charity gala and decides to volunteer.
