Where are the Simpsons? My wife might have the solution

So my wife is probably one of the coolest geeks I know. Would you like to know why?

We were just watching the intro for a new episode of The Simpsons where Comic Book Guy ate a dinner, and finally was given the bill which showed, among other things, the tax. So, she pulled out a calculator, figured out the food service tax percentage, and went straight to Google to see which state Springfield is in.

Does anyone know which State has 8.24% food service tax?
