The best restaurants serving Pizza pasta food in Maidenhead Riverside Windsor and Maidenhead South East

Ordered 2 large pizzas via uber eats for dinner (Texas BBQ) as expected we ate the first pizza and kept the left overs for the next day.. once we moved the extra slices onto a plate we noticed a purplish coloured stain to the pieces of chicken.. is this mould? It certainly looks very suspicious and snapped a few photos.. I would really like some feedback from dominos about this…very disappointing 😳
