There is a stereotype of Americans traveling and doing two things, complaining that the local coffee is not good, and seeking out McDonalds. I am an oddball in many ways, but I think the coffee in Europe is far better than the weak, bitter swill that most places serve in north America.
If I have a choice between someplace local, and a chain, if I am at home, or halfway around the world, I generally try the local place. Our first day in Dublin, we wandered a couple of blocks from the hotel in search of our first meal after arrival. The Oval bar fit the bill, and the food was amazing. As I recall I had Irish Stew, one of the specials, it was great. A hint, for local food, in small places, go for the special. It is often what was fresh, easy, good. Sometimes it is a great price, sometimes it is special because it has rare and pricey ingredients. They tend to feature it because they know people will like it and come back. It is also often something that is quick to serve.
McDonalds, I have a few times. But not recently.
