The city centre has got to fancy for just basic breakfasts (where you can pick out the veggie bits and just order them), all the restaurants serve complicated egg based dishes that can't be modified, so you are left with toast and jam or maybe not even that!
I tried to google vegan brunch places in Dublin but none of the suggested places open early enough, so now I just meet for coffee instead!
So again, you aren't trying to save money specifically, but you end up saving because there is nothing on the menu you want to eat!
Today's coffee €3.20
