There are few foods that really compare to drunk foods. Nothing tastes so good as a pile of cheesy carbs that you ingest like a ravenous bear after you've had a few drinks. Sure, cheese fries are a good option here, but you generally have to be at a restaurant to get the kind that are worth having. Nachos are always great, but I think I can speak for everyone here when I say that Taco Bell is nobody's friend. We've all been betrayed too many times by that place. So, that leaves you one option.
Pizza is a glorious thing. But so many of the chains stop delivering at what people would term "a decent hour." So, what are you left with when it's midnight, you're drunk, and you need a pizza? If you're in Norman, you call Pizza Shuttle.
