This document has a good breakdown of where your city taxes go:

On page 72, it has a chart showing the distribution of the typical $176.80 monthly tax bill. Why they did it that way rather than a simple percentage, I don't know, but it still gives you an idea of where the money goes.
There are only 4 categories that get more than 10% each. The biggest by-far is the Police, which gets $21.50 from every $100 you pay. Transit is next at $16.06 per $100. Then Fire at $12.52 per $100. Finally, Enabling Services (which is things like insurance, HR, IT, etc. that are required to be able to do all the other stuff) amounts for $12.27 per $100.
Combined, those 4 areas take up $62.35 from every $100 you send to the city. Realistically, if you want to see a significant reduction in your taxes, those are the areas that need to see the cuts.
