Update: I stopped in, hungover as all hell, on my way to the airport.
Other than the Build-you-own-burger going up in price ($3.99 now), everything was the same.
There was the same super-friendly service, the same delicious spicy bloody marys from the bar, and the same juicy burgers and fiery hotwings. I brought my grandmother for her first time, and she was impressed. That's a good sign.
Dear Badger Cafe, please open a new location in Nashville. Love, Heather
