When you find yourself really hungover anywhere near Powell, please consider the Lotsa Luck Tavern...
20 oz Pabst and burgers that they put cheese on BOTH sides of the patty. I don't understand why no one else adopts this practice. Seriously genius. You really have to be in the right state of mind to step to this place. Opt for the mushrooms and swiss. Pretty inexpensive.
My cohort braved the addition of the over-medium egg and required nap shortly thereafter.
