I haven't seen 1 for 1 anywhere. All the restaurants in OV take credit cards. All of our lunchtime options have been cash only. We have been averaging around €80 for dinner for the 2 of us which generally includes a bottle of wine. The food has been simply wonderful everywhere we've gone. OV has been very alive every night that we have been here with all of the restaurants being nearly full. Oh, and tips have all been in cash.
