The definition of a dive bar

A great dive bar obeys a number of principles, walking a fine line between a standing health code violation and the place you want to be on any given night. It’s time to elucidate some of those principles in this space, so you can know if your favorite spot can be classified as a dive.
A dive bar always has a shot and a beer special, but that never includes top shelf liquor or beer on tap.
A dive bar is never a place you go to eat, but always has one food item that you look forward to eating after a few drinks — be this a packaged snack or a square pizza.
A dive bar always possesses a leisure activity, which is either never in use or not working exactly right — such as a pool table that leans or trivia machine that eats your quarters.
