Mm and another thing that might help..
Hopefully the image isn't TOO confusing. But if you follow empty spaces left/right/up/down you can also eliminate some (read: a lot of) things.
Hot Dog can only be 12:00 or 12:15. Because Vincennes and Wilbur are neither 12:00 nor 12:15, they cannot be Hot Dog.
Francis can only be 12:00 or 12:15. Because Chicken Wing is neither 12:00 nor 12:15, Francis cannot be Chicken Wing.
There's a vertical example in your puzzle as well.. involving Vincennes and Chicken Wing, if you can spot it.
