Great franks, fries and onion rings Jack, but you do not have the best chili in New Jersey my friend, not enough body or spice there.
Good hot dog chili has to stand on it's own and be just good chili, without the dog. Right now your claim is but an empty boast.There are people out there that are serious about their chili and anyone that agrees with your claim is either a relative, friend or employee.
Have a chili cook off and offer to add the winner's creation to your menu as a condiment and menu selection and see what happens. Chili freaks will come out of the woodwork! Just a thought Jack.
Another suggestion is better signage. If not for the hot dog mascot you initially used to advertise your location I would have never become one of your happy customers.
