Based on my sample size of the one Dominoes restaurant in Nijmegen (Netherlands): it is better outside of the US. Still not great, but better. The chicken shoarma pizza could possibly be considered ‘good’ if it were fresh, but that location only does delivery so…
I have to nitpick slightly; Holland is not a country. Amsterdam is in the North Holland province of the Netherlands.
