I prefer McDonalds when abroad mostly because of their ordering machines. It's a big advantage if you travel to a non-English speaking country. I was able to order food without friction in Estonia, Finland, Italy, without speaking any of their languages.
People there will be happy to try to speak English to you if you let them. I don't speak Italian, Finnish, or Estonian for that matter, but I've been there and I have never had a problem communicating with people in the hospitality industry.
