Well, just back from visiting Belgium, Luxembourg and Amsterdam.
I can happily report that both McDonalds and Burger King are doing quite well across the pond. I have never seen a bigger, more elaborate Burger King than I saw along the motorway to Brussels - here you can still have it your way! At McDonalds, meanwhile, the $1 value meal is the 1 euro meal. That means it cost me $1.20 or so given the current exchange rate. They also include some sort of liquid yogurt in the kids meals....not that appealing, really. And, guess what? The french fries at Mickey D's (I always thought they were really good) are not even close to the frites you can get most everywhere in Belguim - they eat theirs with a special mayonnaise (and it it goooooood!).
I found it interesting how few franchise operations I saw. I did see a Midas in Brussels, and several Pizza Huts lurking in the shadows...but overall, American franchises just don't seem to catch on over there, or at least it seems that way by my scientific research (ie; driving around).
It seems that in these countries, the independence of having your own name on the door is more important than the franchise, and the reputation of the joint is the key to success.
In fact, I think being unique in these countries is preferred - and having a common identity is almost a bad thing.
