There are public toilets and then there are toilets that you can access if you look hard enough.

It's always good to keep a mental list of where it's good to take a leak no matter where you are in the city. Small resturants, old places you used to work, fancey hotels, friends houses etc etc are a wealth of clean bowls

Kinda like you find good places to eat, you also have to find good places to pee.
