For what it's worth...
I wasn't in Dublin, so I don't know the issue there.
Was the problem like in Vienna?
For me, the issue in Dublin wasn't that there were no places to eat, but
that there were very few places to eat, and they were small, and we filled
them up. I could walk, eat lunch, and return in 1.5 hours, but couldn't
stand around waiting to be seated, or wandering around to other places to
eat, and discovering that they were also full.
So I ate in the hotel in Dublin much more than I prefer at an IETF.
