Hi! Are credit cards accepted in most touristy spots in Paris such as paying at non-fancy restaurants, entrance fees at the museums/attractions, metro/RER, grocery stores, etc? Or it's mainly cash? Also, is VISA generally accepted everywhere in Paris or is Mastercard used more in Europe? My credit card does not charge fees when I use the card outside the US. We will also carry some cash but would prefer the simplicity of credit cards and get those points :-)
Thanks for the advise!
