The ease of use, quick integration with POS systems (both restaurant side as well customer).
They are constantly adding new features to make this system better than others out there! There really isn't anything I dislike about ready at all - it's very user friendly once you become familiar w/ their layout & how things work in general terms. Overall great experience so far. We have been able solve our issues related tot he lack or availability / time constraints we had previously when dealing directly wit clients' payments from an external processor such us SquareUp etc..
