Here's one I thought up.

Dr. Fizzwidget's Soda Parlor

Back in the sixties, this pharmacy/soda fountain was the hipe of the city. The Owner, Dr. Harvey Fizzwidget is an old eccentric man with the tendencies for using ridiculous made up words like hornslanger or discombobulajaded (dis-com-bob-you-la-jaded). He's a healthy old man, having bought the pharmacy in the sixties as an old man. He refuses to say how old he truly is, but that's half the old coot's charm.
The Soda Parlor today is still half-diner and half-pharmacy like it was in it's prime. The chef behind the griddle is a huge Polynesian by the name of Reese "Peanut Butter Cups" Toanka. He's a big fun loving guy, with a love for the sweet he gets his nickname from, but more than one he's kicked a ruly teenager out by the cuff of his shirt, and a cleaver pointed at his head.
